Question

The angles of a quadrilateral are in the ratio 1:2:3:4. What are the measure of the four angles

Answer 1

Answer:

let the common factor be x

the angles are 1x,2x,3x,4x.

summation of all angles of a quad. is 360°

1x+2x+3x+4x=360°

10x=360

x=360÷10

x=36°

1x=1×36=36°

2x=2×36°=72°

3x=3×36°=108°

4x=4×36°=144°

the angles are 36°,72°,108°,144°.
