Question

Angle a and b are supplementary,angle a is 32 What is angle b?

Answer 1

By definition, two angles are called supplementary when their measures add up to 180 degrees.

Given:

angle a and b are supplementary

a = 32

Using the definition above:

$\begin{gathered} a\text{ + b = 180} \\ 32\text{ + b = 180} \\ \text{Collect like terms} \\ b\text{ = 180 -32} \\ b=148^0 \end{gathered}$

Answer:

b = 148
