Answer:
29 degrees
Explanation:
If I read your question correctly, your degree measures were
35, 52, and 3(x+2).
We know that all triangle angles measure up to 180 degrees, so we can add all of the given degree values to 180.
35+52+3(x+2)=180
Now, we can solve for x.
87+3x+6=180
93+3x=180
3x=87
x=29
