A side of the triangle below has been extended to form an exterior angle of 135°. Find the value of x.
Left: 112. Right: 135.
The exterior angle of a triangle is equal to the sum of the opposite interior angles. So, in this case, we have:
135 = 112 + x
To solve for x, we can subtract 112 from both sides of the equation:
135 - 112 = 112 + x - 112
23 = x
Therefore, the value of x is 23.
