Question

Q.16 The ratio of four angles of a quadrilateral is 3:7.5:9. Find the angles.​

Answer 1

Answer:

45°, 105°, 75° and 135°

Step-by-step explanation:

Let the ratio be 3x : 7x : 5x : 9x.

According to Question,

3x + 7x + 5x + 9x = 360

=> 24x = 360

=> x = 360/24

=> x = 15

Hence, the angles are 45°, 105°, 75° and 135°.

Answer 2

Answer:

3x + 7x + 5x + 9x =180°

24x = 180°

x= 180/24
