Answer:

• Given - angles of a quadrilateral is in ratio of

3: 5: 9 : 13

• To find - all angles

• Solution

Let the ratio be

3x , 5x , 9x ,13 x

We know that sum of all angles of a quadrilateral is 360°

3x + 5x + 9x + 13x = 360

30x = 360

x = 360/30

x = 12°

All angle are -

3x = 3 × 12 = 36°

5x = 5 × 12 = 60°

9x = 9 × 12 = 108°

13x = 13 × 12 = 156°

Answer:

the answer will be x=12

Step-by-step explanation:

the sum of all sides in a quadrilateral is 360

then we will add all the given ratios the sum will be 30

and when we divide 360/30 so x will be 12

and 3×12=36

5×12=60

9×12=108

13×12=156
