a. So remember that the total degrees in a triangle is 180 degrees. If we use this fact, we can solve for x! 

Let's set up an equation to help solve for x. If you add up all the angles, you should get 180, so: 

3(x+2) + 52 + 35 = 180. 

So you should get 3x + 6 + 52 + 35 = 180. If you simplify it, you'll get:
3x + 93 = 180.

I'll let you go ahead and solve for x. Let me know what you come up with. 

2. Once you get a number for x, go ahead and plug it into 3(x+2) to get the measure of angle C. 

Let me know if you have any trouble. 
All the angles in a triangle add up to 180 degrees. So 35 + 52 + 3(x + 2)= 180. Solving this equation gets you x=29. Therefore 3(29+2)=93, so angle c=93. Hope this helps!
