Question

Find the value of the unknown exterior angle $x$in the following diagram.

Answer 1

Finding the Value of $x°$

Given figure

We have to find the value of the exterior angle $x$

By the exterior angle property of the triangle, we have

$$\begin{gathered} Exteriorangle=sumofinterioroppositeangles \\ \Rightarrow x=50°+70° \\ =120° \end{gathered}$$

Hence the value of the exterior angle $x$ is $120°$
