Question

A pair of consecutive (adjacent) angles of a parallelogram are in the ratio 2:3. Find each angle of the parallelogram​

Answer 1

SOLUTION

• Let one angle = 2x
• Second angle = 3x

• Sum of opp. side og triangle = 180
• 2x + 3x = 180
• 5x = 180
• x = 36

Each angles are alternate

=2x = 2x36 = 72

=3x = 3× 36 = 108

Answer 2

Answer:

2:3=72,108

Step-by-step explanation:

Sum of two adjacent angles of parallelogram =180

Let angle first =2x

and second angle=3x

so,

2x+3x=180

5x=180

x=180/5

x=36

Now, first angle=2x=2*36=72

second angle=3*36=108
