ANSWER
x = 75 degrees
EXPLANATION
We have a triangle with three angles.
Two angles are given as 58 degrees and 47 degrees.
The total angle in a triangle is 180. This means that the angles in a triangle sum up to give 180 degrees.
Therefore:
58 + 47 + x = 180
105 + x = 180
Collect like terms:
x = 180 - 105
x = 75 degrees
That is the value of x.
