What is value of x? <br> See picture
morpeh [17]

Answer:

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 = \frac{180-38}{2} = \frac{142}{2} = 71
