Find the value of y. 70 Solution Notice that y represents the measure of a base angle of an isosceles triangle. From the base angle has the same measure. The vertex angle forms a linear pair with a 70° angle, so its measure is Theorem, the other 110° + 180° Apply the Triangle Sum Theorem. %3D y = Solve for y.
