Answer: x = 78°

Explanation:

The attached photo gives detailed illustration of the given diagram.

Looking at the diagram in the attached photo,

Line m is parallel to line n. It means that ∠ y and ∠ 23 are alternate angles. Since alternate angles are equal, then ∠ y = 23 degrees.

∠w + 79 = 180° (sum of the angles on a straight line is 180 degrees)

∠ = 180 - 79 = 101°

The sum of the angles in a triangle is 180°. Therefore,

w° + z° + 50° = 180°

z° = 180 - 50 - 101

z = 29°

y° + x° + 50° + z° = 180°

Therefore

23 + x° + 50 + 29 = 180°

x° + 102 = 180

x° = 180 - 102

x = 78°
