Question 1048510: The sum of the measures of the angles of a parallelogram is 360°. In the parallelogram on the right, angles A and D have the same measure as well as angles C and B. If the measure of angle C is four times the measure of angle A, find the measure of each angle. Answer by jorel555(1290) (Show Source):
You can put this solution on YOUR website! Angle A=angle D, and C=D. Let n=angles a and d. Then b and c are 4n. So:
4n+4n+n+n=360
10n=360
n=36
Angles A and D are both 36°, B and C are 144°. ☺☺☺☺
