Hello! Could someone help me please :D will name brainliest!! If correct answer:D

Answer:

m∠D = 49°
m∠E = 41°
m∠F = 90°

Step-by-step explanation:

        We know a triangle's angles add up to 180, so we can create an equation and solve for x. We also know the little box represents 90 degrees.

Given:

        90° + 5x° + 14° + 3x° + 20° = 180°

Combine like terms:

        8x° + 124° = 180°

Subtract 124 from both sides of the equation:

        8x° = 56°

Divide both sides of the equation by 8:

        x = 7

        Now, we will plug this value of x back into the angles to solve. Again, the little box represents that Angle F is equal to 90 degrees.

m∠D = 5x° + 14° = 5(7)° + 14° = 49°
m∠E = 3x° + 20° = 3(7)° + 20° = 41°
m∠F = 90°

It should be noted that z^4 will be -32 in rectangular form.

Based on the information, z = r(cos θ + i sin θ), and provided positive integer n, then it is implied that:

z^n = r^n (cos nθ + i sin nθ)

In this instance, we need to solve for z^4 in rectangular form when z = -2 - 2i. Firstly, we must calculate |z| and arg(z):

|z| = √((-2)^2 + (-2)^2) = 2√2

arg(z) = arctan(-2/-2) = π/4

Leveraging De Moivre's theorem, we can effectively deduce the value of z^4 as:

z^4 = (2√2)^4 (cos (4π/4) + i sin (4π/4))

= 32 (cos π + i sin π)

= -32

Concludedly, z^4  resolved in rectangular form is -32.

Angles forming a triangle sum to 180°

On September 16, 2011, U.S. President Barack Obama approved the Leahy-Smith America Invents Act (AIA). The AIA changed U.S. Patent law from a first-to-invent system to a first-to-file one following years of dispute.

The first inventor of the claimed invention may be given a patent, according to long-standing U.S. patent law. The goal of this rule was to provide equal opportunity for small businesses to compete with "the big dogs" in the field of developing technology.

The argument was that these tiny, occasionally one-person operations lacked the legal infrastructure required to prepare and submit patent applications in a timely manner. The costs of establishing inventorship in front of the U.S. Patent and Trademark Office (USPTO) or federal judges may have, regrettably, outweighed the advantages of the first-to-invent system. In order to prove their claims in one forum or another, the creators of competing technologies ultimately had to navigate a maze of rules and standards. These legal actions were expensive for many small businesses.

Yes, because both figures are rectangles and all rectangles are similar.

A rectangle is a four-sided polygon with four right angles. It is one of the most common shapes in both two-dimensional and three-dimensional geometry and can be found in everyday objects such as windows, doors, and tables. Rectangles are also found in nature, like rivers, beaches, and mountains. The area of a rectangle is the product of its length and width, while the perimeter is the sum of its four sides. Rectangles are also special cases of other shapes such as squares and parallelograms, as they are the same shape but with different lengths of sides.

The height of the second square base prism is 50 cm.

The volume of the first square base prism is represented as follows:

v = ha²

where

Therefore, the height of the prism is 10 cm.

v = 10a²

Hence, the volume of the initial prism is 5 times the volume. Therefore,

v = 5(10a²)

v = 50a²

Therefore,

50a² = ha²

divide both sides by a²

50a² / a² = ha² / a²

50 = h

h = 50  cm

Therefore, the height of the second square base prism is 50 cm.

Answer:

No

Step-by-step explanation:

If you think about this, we can figure out that 66 is 2/3 of 99.

To find out what 2/3 of 125 is, we can divide 125 by 3.

125 ÷ 3 = 41.6666667

Now multiply that by 2:

41.6666667 × 2 =83.3333334

So, no.

This is not proportional.

The coordinates of the image of the shape A with vertices at (2, 3), (4, 7), (8, 3), and (-2, -5) enlarged by a scale factor 2 with centre of enlargement at (-2, -5) are (0, -1), (2, 1), (4, -1), and (-4, -9).

Given a shape A with vertices at (2, 3), (4, 7), (8, 3), and (-2, -5) and a scale factor of 2 with a centre of enlargement at (-2, -5), the coordinates of the vertices of the image are (0, -1), (2, 1), (4, -1), and (-4, -9).

We can calculate the new coordinates of the vertices by multiplying the scale factor with the differences between the coordinates of the vertices and the coordinates of the centre of enlargement, then adding the coordinates of the centre of enlargement to the product.

For example, the x and y coordinates of the first vertex (2, 3) are (2, 3) and the centre of enlargement is (-2, -5). So, the difference between the two is (2 - (-2), 3 - (-5)) = (4, 8). Multiplying the scale factor 2 with the differences gives (4 * 2, 8 * 2) = (8, 16). Adding the centre of enlargement to the product gives (8 + (-2), 16 + (-5)) = (6, 11). Therefore, the coordinates of the image of the first vertex is (6, 11).

Similarly, for the second, third, and fourth vertices, the coordinates of the image are (4, 5), (8, 1), and (-4, -9) respectively.

Step-by-step explanation:

Jamal would need approximately 7.9 gallons of gas to travel 296.25 miles.

We can use the concept of direct variation to solve this problem. Direct variation means that two quantities are related by a constant ratio. In this case, the number of miles driven is directly proportional to the number of gallons used.

To find the constant of proportionality, we can use the given data. From the table, we can see that when Jamal used 14 gallons, he drove 525 miles. So we can write:

14/525 = k

where k is the constant of proportionality.

Solving for k, we get:

k = 14/525

Now we can use this value of k to find how many gallons Jamal would need to travel 296.25 miles. Let x be the number of gallons he would need. Then we can write:

x/296.25 = k

Substituting the value of k, we get:

x/296.25 = 14/525

Solving for x, we get:

x = (296.25 × 14) / 525

x ≈ 7.9

The measure of the complement of angle XYZ is: 55°.

The complement of an angle is the angle that, when added to the original angle, forms a right angle (90 degrees). The complement of an angle is also known as the complementary angle.

For example, the complement of a 45-degree angle is 45 degrees because 45 + 45 = 90. The complement of a 30-degree angle is 60 degrees because 30 + 60 = 90.

The complement of an angle is often used in geometry and trigonometry to solve problems involving angles in triangles and other shapes. It is also used in everyday life, such as when hanging a picture or constructing a building, to ensure that the angles are properly aligned.

Thus, given that angle XYZ measures 35°, to find the complement of angle XYZ, subtract 35 from 90 degrees.

Therefore:

Measure of the complement of angle XYZ = 90 - 35 = 55°.
