Question

If an angle of a parallelogram is four times its adjacent angle, then find the measure of these two angles of the parallelogram.

Answer 1

Answer:

let one angle be x

the adjacent angle be 180-x

x=4(180-x)

x=720-4x

x+4x=720

5x=720

x=144

one of the angle is x=144

and its adjacent is 180-x= 180-144=36
