Question

The angle of quadrilateral are the ratio 1:4:5:8 find the angles of quadrilateral Name the quadrilateral

Pls tell correct and fast

Answer 1

Answer:

let the ratio be x.

then the angles are x,4x,5x,8x

sum of all angles of quadrilateral is 360°

x+4x+5x+8x = 360°

18x = 360°

x = 360°/18

x = 20°

<1 = 20°

<2 = 4x = 80°

<3 = 5x = 100°

<4 = 8x = 160°
