Question

21 and 22 are complementary angles. Given mZ1 = 83º , find m22.10m22ok

Answer 1

We have the following:

when two angles are complementary, the sum of these is equal to 90 degrees, therefore

`\begin{gathered} <1+<2=90 \\ <1=83 \end{gathered}`

solving for <2

`\begin{gathered} 83+<2=90 \\ <2=90-83 \\ <2=7 \end{gathered}`

That is, <2 is equal to 7 °
