Question

difference of two supplementary angles is 45° .find the lower angle.

Answer 1

If sum of any two angles equals 180degrees

then they are called supplementary.

Let one angle = x

Its supplementary angle = 180 - x

According to the problem given,

Difference of supplementary angles = 45

x - ( 180 - x ) = 45

x - 180 + x = 45

2x - 180 = 45

2x = 45 + 180

2x = 225

x = 225/2

x = 112.5

Therefore,

Required angles are ,

x = 112.5  degrees

180 - x = 180 - 112.5  = 67.5 degrees
