Question

Just help thank you

Answer 1

Answer:

12

Step-by-step 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

$\frac{6x}{6} = \frac{72}{6}$

Calculate

$x = 12$

Hope this helps...

Best regards!!

Answer 2

Answer:

x = 12

Step-by-step explanation:

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

6x + 48 + 60 = 180

6x = 72

x = 12
