Answer:

x= 10

Step-by-step explanation:

We can use the fact that the sum of all angles in a triangle is 180°.

5x +7x +60 = 180

Solve for x, because we have 1 equation with 1 unknown

   5x +7x +60 = 180, combine like terms

       12x + 60 = 180. subtract 60 from both sides of the equation

12x + 60 -60  = 180 -60, combine like terms

                12x = 120, divide both sides by 12

                   x = 10
