Question

An angle measures 84° less than the measure of its supplementary angle. What is the measure of each angle?

Answer 1

Answer:

132,48

Step-by-step explanation:

Supplementary angles add to 180

Let x be the 1st angle

x-84 be the second angle

x +x-84 = 180

Combine like terms

2x-84 = 180

Add 84 to each side

2x-84+84 = 180+84

2x = 264

Divide by 2

2x/2 = 264/2

x = 132

The other angle is 132-84 =48

Answer 2

Answer:

48°, 132°

Step-by-step explanation:

Let the supplement angle be x

x + (x - 84) = 180

2x = 264

x = 132

x - 84 = 48
