Question

The angles 3x+6 and 5x + 6 are supplements. What are the two angles

Answer 1

Answer:

x = 21

Step-by-step explanation:

Step 1:  Make an expression

Since they are supplements, that means that they add up to 180 degrees.

3x + 6 + 5x + 6 = 180

Step 2:  Combine like terms

3x + 6 + 5x + 6 = 180

(3x + 5x) + (6 + 6) = 180

8x + 12 = 180

Step 3:  Subtract 12 from both sides

8x + 12 - 12 = 180 - 12

8x = 168

Step 4:  Divide both sides by 8

8x / 8 = 168 / 8

x = 21

Answer:  x = 21
