Answer:
34 degrees.
Explanation:
First of all, the sum of a triangle's degree is 180.
The angle next to the 101 is 79 degree due to the rule of supplementary angle. The angle vertical to 28 is also 28. (Vertical angles are equal).
Now we now the two side, we can figure out the last side.
180-28-79= 73
The last angle is 73 degrees. However, we are looking for x.
x+39=73
All we have to do now is subtract 39 from 73, and that leaves us with 34.
