Answer:

C = 125

Step-by-step explanation:

Since a straight line is 180 degrees. We can conclude that:

10x + 15 + 5x = 180

And that:

C = 10x + 15

First we need to find the value of x to find C. So,

10x + 15 + 5x = 180

15x + 15 = 180

       - 15    -15

15x         = 165

15x/15     = 165/15

x              = 11

So now, we need to substitute the values of x into C and solve it.

C = 10(11) + 15

   =  110 + 15

   = 125
