Let the measure of angle be 'x'
Since, the measure of the supplement of an angle is 84° less than the measure of the angle.
Therefore, measure of supplement of x = x - 84°
The measure of two supplementary angles is 180 degrees.
So, the measure of angle =
Its supplement = x - 84° = 132° - 84°
= 48°
So, the measure of supplement of angle is 48 degrees.
