A side of the triangle below has been extended to form an exterior angle of 112°. Find the value of xx. 112° x°
The sum of the exterior angles of a triangle is always 360 degrees. Since one of the exterior angles is given as 112 degrees, we can find the value of x as follows:
112° + x° + 68° = 360°
x + 180 = 360
x = 360 - 180
x = 180
Therefore, the value of x is 180 degrees.
