Question

If the aangles of a five sided ploygon are in the ratio of 2:3:3:5:5, what is the measure of the smallest angle

Answer 1

let the angles be 2x,3x,3x,5x,5x.

sum of angles= 540

2x+3x+3x+5x+5x=540

18x=540

x=540/18

x=30

2x=2×30=60

3x=3×30=90

5x=5×30=150

The measure of the smallest angle=60
