Hey there! :)

Answer:

x = 89°.

Explanation:

x + 42 is supplementary to the inside angle at the top of the triangle, so:

The top angle of the triangle is equal to:

180 - x - 42.

All of the angles in a triangle add up to 180°, therefore:

180 = x + x - 47 + 180 - x - 42

Combine like terms:

180 = 2x + 133 - x - 42

180 = x + 91

Subtract 91 from both sides:

89 = x.

Therefore, x = 89°.
