Question

The angles of a quadrilateral are in the ratio 1:1:3:7. The largest angle of the quadrilateral is

Answer 1

Given ratio of angles are 1:1:3:7

So let angles are x , x , 3x and 7x

we know that,

Sum of all angles of quadrilateral is 360 dgree

According to the question,

x + x + 3x + 7x = 360

2x + 10x = 360

12x = 360

x = 30

.°. The angles are

• x = 30°

• x = 30°

• 3x = 3 × 30 = 90°

• 7x = 7 × 30 = 210°

The largest angle is 210°
