Question

The Exterior Angles Of A Quadrilateral Are $50°,80°,X,120°.$ Find The Value Of $X.$

Answer 1

As we know, the sum of exterior angles is $360°$

$$\begin{gathered} \therefore 50°+80°+X+120°=360° \\ 130°+X+120°=360° \\ 250°+X=360° \\ X=360°-250° \\ X=110° \end{gathered}$$

Therefore, the value of $X$ is $110°$
