Question

In the figure below, m∠R is 66°, and m∠T is 130°.


What is m∠Q?

Answer 1

The correct answer is D 64°

Explanation:

S is equal to 50 because we have a straight line (angle). A straight angle is 180°. 180 -130 = 50°.

If angle s = 50° and angle R = 66° (given), then Q must be 64°.
This is true because the sum of the interior angles or a triangle is 180.

180 - 50 - 66 = 64
