Question

if an angle of a parallelogram is two-third of its adjacent angle,find the angles of the parallelogram?

Answer 1

Let x and y be the two angles of aparallelogram. It is given that oneangle is two-third of its adjacent angle. So, we assume that angle "x" istwo-third of angle "y" . ... It means that the sum of adjacent angles is equal to 180.

Answer 2

Let x and y be 2 angles of a parallelogram

Given x = 2y/3

Also, these angles are supplementary (adjacent angles)

x+y =180

5y/3 = 180

y = 108 degrees

x= 72 degrees
