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.


  • x+39=(x+x)+(-16)

  • x+39=2x-16

Step 2: Subtract 2x from both sides.


  • x+39-2x=2x-16-2x

  • -x + 39 = -16

Step 3: Subtract 39 from both sides.


  • -x + 39 - 39 = -16 - 39

  • -x = -55

Step 4: Divide both sides by -1.


  • (-x)/(-1) = (-55)/(-1)

  • x = 55

Step 4: Check if solution is correct.


  • (55)+39=(55)-16+(55)

  • 94 = 39 + 55

  • 94 = 94

Therefore, x = 55.
