Option b is correct
x=1.75
Answer:
x = 71°
Step-by-step explanation:
The triangle is clearly an isosceles triangle.
We know that all interior measures of a triangle must add up to 180°.
So: 180° - 38° = 142°
Because it is an isosceles triangle, the other two missing angles must be equal.
142° ÷ 2 = 71°
