Question

angle of a qualdrilateral is in the ratio of 5:4:2:1 then find the greatest and smallest angle

Answer 1

Answer:

let the angle=x

the sum of angle of t qualdilateral is 360°

5x+4x+2x+x=360°

12x=360°

x=360°/12

x=30°

5x=150°

4x=120°

2x=60°

x=30°

longest angle=150°

shortest angle =30°
