Answer 2

Given:

Refer the question image,

Find the value of $x$.

Solution:

Know that,

The measure of angles opposite to the equal side are equal.

The measure of exterior angle is to the sum of the other two angles.

Therefore,

$\[\begin{array}{l} \Rightarrow x^\circ + x^\circ = 110^\circ \\ \Rightarrow 2x^\circ = 110^\circ \\ \Rightarrow x^\circ = 55^\circ \end{array}\]$

Hence, the measure of angle $x$ is $\[55^\circ \]$
