Question

If the ratio of measure of two adjacent Angeles of a parallelogram is 1:2 find the measure of all angle of the parallelogram

Answer 1

60° and 120° is the angle

Answer 2

Given :

• Adjacent angles are in the ratio of 1:2.

To find :

• The angles

According to the question,

Let,

The angles be 1x and 2x

And adjacent angles of a parallelogram is 180°

➞ 1x + 2x = 180°

➞ 3x = 180°

➞ x = 180° ÷ 3

.°. x = 60°

____________....

Value of 1x :

➞ 1x

➞ 1 × 60°

➞ 60°

____________....

Value of 2x :

➞ 2x

➞ 2 × 60°

➞ 120°
