the measure of two adjacent angles of parallelogram are in the ratio 3:7 find the measure of each angle of parallelogram

from the pararellelogram has 4 angles is 180° and each 2 angles of this is equal so the ratio is 3:7 it will be 3x and 7x.

from each 2 angles is equal it will be 3x+7x = 180/2 so 10x=90; x=9

Substitute x=9 in 3x and 7x; the angles is 27 and 63
