Question

Find the value of each angle in the given figures:

Answer 1

Step: Find value of x

By the angle sum property of the triangle,

$x^{\circ }$ + ${90}^{\circ }$ + $x^{\circ }$ = ${180}^{\circ }$

$2x^{\circ }$ = ${180}^{\circ }$-${90}^{\circ }$

⇒ $2x^{\circ }$ = ${90}^{\circ }$

⇒ $x^{\circ }$ = ${45}^{\circ }$

Hence, the unknown angle $x^{\circ }$ is ${45}^{\circ }$.
