Question

The sum of two adjacent angles is 140. If one angle is thrice that of the other . Find the two angles

Answer 1

Let obr angle be x

so x + 3x =140

4x=140

x=35

So the angles are 36 and 105

Answer 2

let the smaller angle be x
therefore larger angle is 3x
A. T. P
3x+x=140
or, x=140÷4=35 degree
