Question

Just help thank you

The angles below are supplementary.
What is the value of x?
2
7
12
18

Answer 1

x = 12

Explanation:

The measures of supplementary angles have a sum of 180 deg.

6x + 48 + 60 = 180

6x = 72

x = 12

Answer 2

12

Explanation:

As we know that the sum of supplementary angles is 180°

Let's create an equation:

`6x + 48 + 60 = 180`

Calculate the sum

`6x + 108 = 180`

Move constant to R.H.S and change its sign

`6x = 180 - 108`

Calculate the difference

`6x = 72`

Divide both sides of the equation by 6

`(6x)/(6) = (72)/(6)`

Calculate

`x = 12`

Hope this helps...
