Question

If one angle of a parallelogram is 3 times of its adjacent angle so find the all angles

Answer 1

Given :

• One angle of a parallelogram is 3 times of its adjacent angle.

To find :

• All the angles.

According to the question,

• Let one angle be x
• Other angle be 3x
• Adjacent angles of a parallelogram are supplementary ( means 180° )

→ x + 3x = 180°

→ 4x = 180°

→ x = 180° ÷ 4

.°. x = 45°

• One angle is x = 45°
• Other angle is 3x = 3 × 45° = 135°

Answer 2

Answer:

if first angle x

and adjacent angle of parallelogram is be 3x

adjacent angles of parallelogram are supplementary

x+3x=180

4x=180

x=180/4

x=45

first angle of a parallelogram is 45°

and second angle of parallelogram is 45 × 3 is equal to 135°
