Answer 1

Answer:

let ratio be x

3x+4x+5x+6x=360°

18x=360°

x=360°\18=20°

3x=54°

4x=72°

5x=90°

6x=108°

Answer 2

Let the angles be x.

So, it is 3x, 4x, 5x and 6x

Sum of all the angles in a quadrilateral is 360°

3x +4x+ 5x+ 6x =360°

18x = 360°

x = 20°

Therfore angles are

3x= 3 × 20°=60°

4x=80°

5x=100°

6x=120°
