Answer:
x = 70°
Explanation:
There are two vertical and parallel lines h and i. Also, a transversal line g cuts across these parallel lines. The intersection of the transversal line and line h produces an upper right angle of 70° and bottom left angle of x°.
These angles x and 70 are vertically opposite angles, hence:
x = 70° (vertically opposite angles are equal to each other)
