Question

1. The angles of quadrilateral are in the ratio 3:5:9:13. Find alle
quadrilateral dargram​

Answer 1

Answer:

the sum of 4 sides of the parallelogram is 360°

Explanation:

let us take the values of the angles as x

then.

3x+5x+9x+13x=360°

30x=360°

x=12

there fore

3x=3×12=36°

5x=5×12=60°

9x=9×12=108

13x=13×12=156°

hope it helps

Answer 2

answer : 3x = 36°

5x = 60°

9x = 108°

13x = 156°

Explanation:

• angles of Quadrilateral are in the from of ratio as follows 3:5:9:13
• So we can take them as 3x , 5x, 9x, 13x .
• So, the sum of all angles of a Quadrilateral = 360°
• angle A + angle B + angle C + angle D = 360°
• 3x + 5x + 9x + 13x = 360°
• 30x = 360°
• x = 360/30
• therefore x = 12°
• 3x = 3×12 = 36°
• 5x= 5×12 = 60°
• 9x= 9×12 = 108°
• 13x = 13×12=156°
