Question

Q-18 The ratio of the angles of a quadrilateral is 3. 5: 9: 13, find all the angles of this quadrilateral.​

Answer 1

Answer:

Step-by-step explanation:

Let the ratio be $3x: 5x : 9x: 13x$

Sides = 3x, 5x, 9x, 13x

$3x + 5x + 9x + 13x = 360$ (Angle sum property of a quadrilateral)

$30x = 360\\x=12$

3x = 12 * 3 = 36

5x = 12 * 5 = 60

9x = 12 * 9 = 108

13x = 12 * 13 = 156
