Question

The measure of two adjust angle of a parallelogram are in the ratio 6:3 then. Find the measure of each of the angle of parallelogram

Answer 1

Answer:

angles = 60°, 120°, 60° and 120°

Step-by-step explanation:

let the adjacent angles = 6a and 3a

so opposite angles are also = 6a and 3a

sum of the angles = 360°

=> 2(6a+3a) = 360°

=> 2×9a = 360°

=> 18a = 360°

=> a = 360°/18 = 20°

=> 3a = 60°

=> 6a = 120°

Answer 2

Step-by-step explanation:

Let the angles be 6x and 3x

•°• 6x+3x = 180

9x = 180

x = 180 ÷ 9 = 20

6x = 6 × 20 = 120

3x = 3 × 20 = 60
