Question

the angles of a quadrilateral are in the ratio of 3: 4 : 5 : 6. Find its angles

Answer 1

let 3x + 4x + 5+ 6x = 180
18x = 180
x = 10
3×10 = 30
4×10= 40
5×10= 50
6×10= 60

Answer 2

hey dude

let the first angle be 3x
second angle be 4x
third angle be 5x
fourth angle be 6x

sum of all angles of a quadrilateral is 360°

3x+4x+5x+6x=360°
18x=360°
x=360°÷18
x=20°

hence,
first angle=3x= 3*20°=60°
second angle=4x=4*20°=80°
third angle=5x=5*20°=100°
fourth angle=6x=6*20°=120°


hope it helps you
