Question

If the difference between two supplementary angle is 40 degree then find the angles

Answer 1

First angle=x(let)
Second angle =40+x
X+40+x=180
2x+40=180
2x=180-40
2x=140
X=140/2
X=70
First angle (x) =70°
Second angle (40+x)=110°

Answer 2

angle:: x

supplement:: 180-x

--------------------

Equation:

x - (180-x) = 40 degrees

x - 180 + x = 40

2x = 220

x = 110 degrees

180-x = 70 degrees
