Question

The angles below are supplementary, What is the value of x?

Answer 1

Answer: x=12

Explanation:

6x + 48 + 60 = 180

6x + 108 = 180

6x = 72

x=12

Answer 2

x = 12

Explanation:

Supplementary angles add up to 180 degrees therefore (6x + 48) and 60 should add up to 180. Like this:

6x + 48 + 60 = 180

Now solve:

6x + 48 + 60 = 180

6x + 108 = 180

6x = 72

x = 12

Therefore, the answer is x = 12.

I hope this helps!!
