Answer:
x = 55
Explanation:
1. We can use exterior angle theorem to find the value of x. The exterior angle theorem states that the exterior angle of a triangle is equal to the sum of the two remote angles in that same triangle.
- Given the information above, x + 39 = x - 16 + x
2. (Solving)
Step 1: Simplify both sides of the equation.
Step 2: Subtract 2x from both sides.
Step 3: Subtract 39 from both sides.
Step 4: Divide both sides by -1.
Step 4: Check if solution is correct.
Therefore, x = 55.
