Question

adjscent angles of parallelogram are in ratio 3:4 find the measures of all the angles of parallelogram​

Answer 1

We know that the adjacent angles of a parallelogram are supplementary ie,

sum of the adjacent angles is 180°

Let the adjacent angles be 3x and 4x

Then,

3x+4x = 180

7x = 180

x = 180/7 = 25.7 ≈ 26

Therefore the angles of the parallelogram are

26× 3 = 78°

26× 4 = 104°
