Question

Find the value of x in each of the following figures ​

Answer 1

Answer:

x=90

Step-by-step explanation:

this is an isosceles triangle... so two angles are equal

using angle sum property

45 +45+x=180

=> x=90

Answer 2

Step-by-step explanation:

In a isosceles triangle opposite angles of opposite sides are equal

So, Angle BAC=Angle ACB

Angle BAC = 45°

We know that,

Sum of angles in a triangle = 180°

x+45°+45° = 180°

x+45+45 = 180

x +90 = 180

x = 180-90

x = 90

x = 90°
