Question

P.2 Find measures of complementary, supplementary, vertical, and adjacent angles
R2B
The measure of an angle is 145.6°. What is the measure of its supplementary angle?

°

Answer 1

To find the supplementary angle of an angle measuring 145.6°, you can use the following relationship:

Supplementary angles are two angles whose measures add up to 180°.

So, to find the measure of the supplementary angle, subtract the given angle from 180°:

\[
\text{Supplementary angle} = 180° - \text{Given angle} = 180° - 145.6°
\]

\[
\text{Supplementary angle} = 34.4°
\]

Therefore, the measure of the supplementary angle is **34.4°**.
