# Chapter 3 - Section 3.3 - Isosceles Triangles - Exercises: 19

#### Answer

55$^{\circ}$

#### Work Step by Step

The answer is 55$^{\circ}$ because 180-70=110 and because you need two of the same angles divide 110 by 2 and you will get 55$^{\circ}$. Because the triangle is an isosceles triangle you need two angles to be congruent.
