Since the exterior angle of a triangle is equal to the sum of the two opposite interior angles, we know that:
70° = 48° + x°
Solving for x:
70° - 48° = x°
22° = x°
Therefore, the value of x is 22°.
A side of the triangle below has been extended to form an exterior angle of 70°. Find the value of xx.
