Answer:

71

Step-by-step explanation:

its an isosceles triangle, as we can tell from the sides, that means that 2 angles are the same size as well. a triangle has 180 degrees.

180-38=142

142/2=71

check

71+71+38=180

that means x=71 degrees

hope this helps!!

Answer:

x = 71

Step-by-step explanation:

The triangle has 2 congruent sides and is isosceles.

Thus the 2 base angles are congruent, so

x = [tex]\frac{180-38}{2}[/tex] = [tex]\frac{142}{2}[/tex] = 71
