Question

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

Answer 1

let one angle =x
adjacent angle =2x/3
in a parallelogram sum of adjacent angles are supplementary(180degree)
x+2x/3=180
(3x+2x)/3=180
5x/3=180
x =180*3/5

x=36*3
x =108
therefore
the angles in a parallelogram are
108,72,108,72

Answer 2

Answer:

let one angle =x

adjacent angle =2x/3

in a parallelogram sum of adjacent angles are supplementary(180degree)

x+2x/3=180

(3x+2x)/3=180

5x/3=180

x =180*3/5

x=36*3

x =108

therefore

the angles in a parallelogram are

108,72,108,72
