Answer:
The measure of the two supplementary angles are 65 degrees and 115 degrees.
Step-by-step explanation:
The sum of supplementary angles is equal to 180 degrees. Let x and y are two angles such that,

According to given condition,
One supplementary angle is 15 degrees less than twice the other, it means,

Putting the value of x from above equation in equation (1),

Now put the value of y in equation (1), so,

So, the measure of the two supplementary angles are 65 degrees and 115 degrees.
