Question

An angle measure is 72.3 degrees. What is the measure of its complement?

Answer 1

Two angles are complementary when they add up to 90 degrees (a Right Angle).

That means that if two angles, A° and B°, are complementary, they add up to 90°:

`A^(\circ)+B^(\circ)=90^(\circ)`

Therefore, if we have one angle as 72.3°, the complement will be calculated as

`\begin{gathered} 90-72.3 \\ =17.7\degree \end{gathered}`

The complement of 72.3° is 17.7°.
