Answer:
Triangle QAD is an isosceles triangle with angle D as the vertex angle. if measure of angle Q is 7x-2 and measure of angle A is 4x+16, find the measure of each angle.
Base angles of an isosceles triangle are equal.
Angle Q = Angle A
7x-2=4x+16
3x-2=16
3x=18
x=6
Angle Q=Angle A=7x-2=7(6)-2=42-2=40
Angle D=180 degrees-Angle Q-Angle A
Angle D=180-40-40
Angle D=100 degrees
ANSWER: Angles A and Q each measure 40 degrees
and Angle D measures 100 degrees.
