Question

Find the value of x

Answer 1

the answer is option D. 1

Explanation:

since the sides are given equal, the angles opposite to thise sides are also equal. it is an isosceles triangles. the angles other than 2, are 45°. therfore, using anglesum property of a triangle,

angle 2 = 180°- (45° + 45°)

= 180°- 90°

= 90°

given: angle 2 = 90°x

therefore, 90°= 90x

x = 90°/90°

= 1

Answer 2

x=1

Explanation:

Since the triangle is equilateral, the opposite angle is also 45°.

So 180-45-45 = 90x

90 = 90x

x=1
