Question

Angle RST is a right angle. Angle RSU has a measure of 25°.

What is the measure of angle TSU?

25°

45°
65°
75°

Answer 1

Explanation:

Yes the angle Rsu has 25 measure shown on graph the way to show RSU TSU Is 90-25=65

Answer 2

Keywords

complementary angles, right angle

we know that

If two angles are complementary angles, then their sum is equal to a right angle

In this problem

`Angle\ RSU+Angle\ TSU=90\°` -------> by complementary angles

we have

`Angle\ RSU=25\°`

Substitute and solve for Angle TSU

`Angle\ TSU=90\°-25\°=65\°`

therefore

the answer is the option

`65\°`
