What is value of x?
see picture

x = 71

Step-by-step explanation:

Since 2 sides of the triangle are congruent then the triangle is isosceles.

Thus the 2 base angles are congruent

The sum of the 3 angles in the triangle = 180°, so

x = = = 71

Step-by-step explanation:

As two sides of triangle are 21, it is isosceles triangle. So, angles opposite to equal sides are equal.

x + x + 38 = 180   {sum of all angles of a triangle }

2x + 38 = 180

2x = 180 - 38

2x = 142

x = 142/2

x = 71
