A side of the triangle below has been extended to form an exterior angle of 137°. Find the value of xx. 137° x°
The exterior angle of a triangle is equal to the sum of the two opposite interior angles.
Therefore, we have: 137° = x° + 37°
Solving for x, we get:
x = 137° - 37°
x = 100°
So, the value of x is 100°.
