Question

The measure of two adjacent angle of a parallelogram are in the ratio 4:5. the angle are​

Answer 1

Answer :-

Angles are 80° and 100°

Explanation :-

Given :

• The measure of two adjacent angle of a parallelogram are in the ratio 4:5.

To Find :

• Both of the angles.

Solution :

Let,

• First Angle = 4x.
• Second Angle = 5x.

We know that,

Sum of Adjacent Angles = 180°

According to the Question,

➙ 4x + 5x = 180°

➙ 9x = 180°

➙ x = 180 ÷ 9.

➙ x = 20.

Therefore, Angles are :-

• First Angle = 4x = 80°
• Second Angle = 5x = 100°
