Question

Sum of two opposite angle of parallelogram is 130°.Find all angles

Answer 1

Step-by-step explanation:

In a parallelogram opposite sides are equal.

let opposite sides of parallelogram be 'x'

x+x=130

2x=130

x=130/2 = 65

In parallelogram sum of adjacent sides is equal to 180

let one of the side is 'y'

65+y=180

y=180-65

y=115

therefore the four sides of parallelogram are 65,115,65,115
