Best ResponseYou've already chosen the best response.0Hint: isosceles means the base angles are equal. The sum of the measures of the three angles is 180 degrees so the formula for the angles is: x + y + z = 180 where x, y, and z are angles since it is isosceles.. x= y your base angle is given to be 30 + 2z where z is the vertex angle so x = y = 30 + 2z (30 + 2z) + (30 + 2z) + z = 180
