Answer:
x = 45°
Step-by-step explanation:
From the triangle given in the picture,
It's given that two sides of the triangle are equal so the triangle is an isosceles triangle.
By the property of isosceles triangle,
Opposite angles of the equal sides are equal in measure.
By triangle sum theorem,
x + x + 90° = 180°
2x + 90 = 180
2x = 180 - 90
x = [tex]\frac{90}{2}[/tex]
x = 45°
