Answer:
1: x = 29
2: Angle C is 93 degrees
Explanation:
For 1 angle C has to equal 93 degrees since 52 + 35 = 87 and 180 - 87 = 93, and a triangles interior angles add up to 180 degrees.
From there create an equation: 3(x + 2) = 93 then solve
3x + 6 = 93
-6 from both sides
3x = 87
/3 from both sides
x = 29
For 2 just plug in x (29)
3(29 + 2)
87 + 6
93
