Question

Need answer for 3a please. This is for homework :)

Answer 1

Given the supplementary angle below for 3a,

Supplementary angles is 180°,

To find x,

$\begin{gathered} 132^0+2x^0+3=180 \\ 2x^0+135^0=180^0 \\ 2x^0=180^0-135^0 \\ 2x^0=45^0 \\ x=\frac{45^0}{2}=22.5^0 \\ x=22.5^0 \end{gathered}$

Hence, x = 22.5°
