Question

Q1. The four angles of a quadrilateral are in ratio 2 : 3 : 5 : 8. Find the angles.

Answer 1

Step-by-step explanation:

angles of one quadrilateral=360

2x+3x+5x+8x=360

18x=360

X=20

2x=40

3x=60

5x=100

8x=160

Answer 2

$\huge\fbox\red{Answer}$

Let the angles of a quadrilateral be 2x, 3x, 5x and 8x.

The sum of angles of a quadrilateral is 360°

2x + 3x + 5x + 8x = 360°

18x = 360°

x = 360° ÷ 18

x = 20°

So the four angles of quadrilateral are

2x = 2×20 = 40°

3x = 3 × 20 = 60°

5x = 5×20 = 100°

8x = 8× 20 = 160°
