what is the value of x? drawing not to scale.

Both the side are 21 units.
⇒ It is an isosceles triangle.


Property of the angles in a triangle:

Sum of all angles in a triangle = 180°


Find x:

x + x + 38 = 180


Combine like terms:

2x + 38 = 180


Take away 38 from both sides:

2x = 142


Divide by 2 on both sides:

x = 71


x = 71°
