Find the angle complementary to the angle 80°. A. 90° B. 180° C. 10° D. 100°

Complementary angles = two angles that add to 90 degrees.

Let x = the complementary angle

Then x + 80 = the two complementary angles

x + 80 = 90

x = 10 < - - Subtract 80 from each side.

So, the complementary angle is 10 degrees.

Complementary Angles is a pair of any two acute angles that add up to make 90 degrees

90-80 = 10

the angle is 10 degrees

C is the correct answer
