Respuesta :
The angle of x is 71°
Because the triangle in isosceles the two bottom angles will have the same measure.
The angles of a triangle will add to 180° so you subtract 38 and divide by 2.

Answer:
x = 142º
Step-by-step explanation:
The measurements of all of the angles in a triangle always equal 180º.
We can use this formula: x + y = 180º
Now, substitute in the known value(s) into the formula.
x + 38º = 180º
Solve
x = 180º - 38º = 142º
x = 142º
