We have two similar triangles here, which means that all of their angles match up and are the same.

Q = T = 40

R = U = ?

S = V = 63

The measure of a triangles interior angles is 180 degrees.

40 + R + 63 = 180

103 + R = 180

R = 77

The measure of angle R is the first option, 77 degrees.

Hope this helps!! :)

Answer:

Step-by-step explanation:

To Solve, just cube the terms on the right side to see if they go back to the number on the left.

The first part is true because multiplying 11 * 11 * 11 = 1331.

The second part is true because multiplying 5 * 5* 5 = 125.

The third part is false because multiplying 8 * 8 * 8 = 512.

The fourth part is true because multiplying 1 * 1* 1 = 1.
