Question

Reasoning The measure of angle 1 is 25degrees. Find the measure of the angle adjacent to angle 1. The figure is not drawn to scale. Use a pencil and paper. Explain how you know your answer is reasonable.

Answer 1

The adjacent angle is 65°.

Explanation:

∠1 and the adjacent angle are complementary angles. This means they total up to 90°.

We know that ∠1 is 25°, so we just subtract that from 90° to find the adjacent angle.

90 - 25 = 65

Answer 2

The other angle is 65 degrees

Explanation:

The two angles make a right angle, so their sum is 90

25+ x = 90

Subtract 25 from each side

25+x-25 = 90-25

x =65
