Answer and Step-by-step explanation:
We are given an isosceles triangle, shown by the fact that there are two red marks on two sides, indicating that the sides are congruent in length, which means the base angles are congruent as well.
Add the angles together and equal it to 180.
34 + x + 81 + x + 81 = 180
Simplify.
115 + 2x = 180
Subtract 115 from both sides of the equation.
2x = 65
Divide both sides of the equation by 2.
x = 32.5 is the answer.
