Question

Solve :

8) Two adjacent angles of a parallelogram are in the ratio 1: 2. Find the measures of
all the angles of the parallelogram​

Answer 1

Step-by-step explanation:

In a parallelogram the sides are parallel. Hence the adjacent angles are cointerior angles that is they are supplementary.

let the angles be x and 2x.

since they are supplementary

x+2x=180°

3x=180°

x=60°

2x=2×60=120°

Therefore the angles are 60° and 120°.
