Question

the three angle of quardilateral are in the ratio 4:4:1 and the forth angle is 90° find the smallest angle​

Answer 1

Answer:

let the angle be called x

4x + 4x + x + 90 = 360 ( angle sum property of a Quadrilateral)

9x + 90 = 360

9x = 360 - 90

9x = 270

x = 270/9

x = 30

4*30 = 120

4*30 = 120

1*30 = 30

hence the smallest side is 30 degree.
