What is the complimentary angle of 72 degrees

Answer: 18°

Step-by-step explanation:

Complementary angles are any two angles whose sum is 90 degrees. Hence, if angles x and y are complimentary, we can say

x + y = 90°

Therefore, the complimentary angle of 72° is obtained by subtracting 72° from 90°

i. e 90° - 72° = 18°

Thus, the complimentary angle of 72° is 18°

Step-by-step explanation:

If sum of two angles add up to 90°, then two angles are called complementary angles

Let the unknown angle be x

x + 72° = 90°

x = 90° - 72°

x = 18°
