Answer: x = 29 degrees
Step-by-step explanation:
Since we know that a triangle adds ups to 180 degrees, we can add our values up to that. So 180 = 52 + 35 +3(x+2). We would distribute the 3 to get 180 = 52 + 35 + 3x + 6. 180 = 93 + 3x. Get the numbers onto one side so then you get 87 = 3x. Finally divide both sides by 3 to get x = 29.
