Answer:
The correct answer is 15° and 75°.
Step-by-step explanation:
n + n + 60° = 90°
2n + 60° = 90°
2n + 60° − 60° = 90° − 60°
2
n = 30°
2n ÷ 2 = 30° ÷ 2
n = 15°
The first angle measures 15°. Now plug in n = 15° to find the measure of the other angle, n + 60°.
n + 60° = 15° + 60° = 75°
So, the two angles measure 15° and 75°.
