Question 108

In the given figure, find the value of x.

Answer 1

We know that, the sum of all three angles in a triangle is equal to ${180}^{\circ }$
So, $x+{55}^{\circ }+{90}^{\circ }={180}^{\circ }$
$\Rightarrow x+{145}^{\circ }={180}^{\circ }\Rightarrow x={180}^{\circ }-{145}^{\circ }\Rightarrow x={35}^{\circ }$
