Answer 1

From the question

For two supplementry angles

One angle is 5 degree less than 4 times the othe angle

Let one of the angle be x

Then the other angle will be 4x - 5

Hence by supplementary angles

`x+4x-5=180`

solving for x

`\begin{gathered} 5x-5=180 \\ 5x=180+5 \\ 5x=185 \\ x=(185)/(5) \\ x=37 \end{gathered}`

Therefore

One of the angle is 37 degrees

The other angle is

`\begin{gathered} 4x-5=4(37)-5 \\ =148-5 \\ =143 \end{gathered}`

Therefore the supplementary angles are 37 degrees and 143 degrees
