Answer:

x = 12

Explanation:

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

6x + 48 + 60 = 180

6x = 72

x = 12

Answer:

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...

Best regards!!
