Question

The measures of two supplementary angles are in the ratio of 2:3. What are the measurements of the two angles?

Answer 1

`72^0 " & "108^0`

Explanation:

supplementary angles add up to `180^0`

let the angles are in ratio

`"2:3`

`2:3rarr2+3=5" parts"`

`5 " parts "=180^0`

`1" part "=180/5=36^0`

`2:3::2xx36:3xx36`

`::72^0:108^0`
