Answer 1

Answer:

Angles are ⇒ 36°, 60°, 108°, 156°

Step-by-step explanation:

Ratio is 3:5:9:13

Therefore let the angles of quadrilateral be,

3x, 5x, 9x, 13x

Sum of all angles of quadrilateral is 360°

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

30x = 360

x = 12°

Angles are 3x12, 5x12, 9x12, 13x12

Angles are ⇒ 36°, 60°, 108°, 156°

Hope it helps you

Answer 2

let the angles be 3x, 5x, 9x, and 13x

so we know that the sum of all angles of quadrilateral is 360°

so 3x+5x+9x+13x=360°

or 30x=360°

or x = 12°

so the angles are 36°, 60°, 108°, 156°
