What is the measure of each angle

Given:

Let x and y denote the supplementary angles.

Given that an angle measures 102.8° more than the measure of its supplementary angles.

This can be written in expression as,

Measure of two angles:

Since, the two angles are supplementary and the supplementary angles add up to 180°

Thus, we have;

Substituting in the above formula, we get;

Thus, the measure of one angle is 38.6°

Substituting in the equation , we get;

Thus, the measure of the other angle is 141.4°

Hence, the measure of the two angles are 38.6° and 141.4°

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

the answer is d
