Question

Z3 and Z4 are supplementary angles. Given mZ3 = 56° , find m24.m24

Answer 1

We have the following:

when two angles are supplementary, the sum of these is equal to 180 degrees, therefore

`<3+<4=180`

In this case, <3 is 56°, replacing:

`\begin{gathered} 56+<4=180 \\ <4=180-56 \\ <4=124 \end{gathered}`

Therefore, the angle <4 measures 124 °
