Triangles always have a value of 180°
So to solve find what the total of the known sides:
52 + 35 = 87°
Know let's figure out ∠C
180° - 87° = 93°
That answers number (2).
Now to find x, we need to work backwards.
What number times 3 equals 93?
It's 31.
And then we need to subtract 2 instead of adding 2 so it works in the equation which would be 29.
Let's try it out:
3 (29 +2) ----> 3 x (31) ----> 93
Answers:
(1) x = 29
(2) ∠C = 93
Hope this helps!
