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
