Answer:
60°
Step-by-step explanation:
Two angles are complementary if one of the angles is double the other angle find the two angles
Complementary angles mean that the two angles, when added together, equal 90°. Let's call the first angle x, and its second, complementary angle 2x. So, we have x + 2x = 90. ... The second angle, 2x, is just twice the first angle, so its measurement is 60°.
