Question

A quadrilateral angles are in ratio 3:5:9:13 then find all angles of quadrilateral​

Answer 1

Answer:

As you know angle sum of a quadrilateral = 360°

So, 3x + 5x + 9x + 13x = 360°

Or, 30x = 360°

Or, x = 12°

Hence, 3x = 36°, 5x = 60°, 9x = 108° and 13x = 156°

Answer 2

Step-by-step explanation:

3 x + 5 x + 9 x + 13 x = 360 °

30 x = 360 °

x = 12 °

Angle 1 is equal to 3x is equal to 36 degree

Angle 2 is equal to 5 x is equal to 60 degree

Angle 3 is equal to 9 x is equal to 108 degree

Angle 4 is equal to 13 x is equal to 156 degree
