Question

The angles of a quadrilateral are in a ratio 1:2:3:4.the smallest angle is

Answer 1

Let the angles be X, 2x,3x,4x

x+2x+3x+4x=360

10x=360

x=36

The smallest angle here obviously is X

therefore the smallest angle=x=36

Answer 2

Answer:

let 1x 3x 3x 4x

1x+2x+3x+4x=360°

10x=360°

x=360/10

x=36

now,

1x=1×36=36°

2x=2×36=72°

3x=3×36=108°

4x=4×36=144°

the smallest angle is 36°
