Answer:

The measure of x is 80°.

Step-by-step explanation:

When a transversal cuts two or more lines, the angles that are in the same relative position are called corresponding angles. The matching angles are equivalent when the lines are parallel.

∠ CBD = ∠ ABF (corresponding angles)

∠ BFE = x°

And ∠ BFE + ∠HFG = 180 (linear pair)

x + 100° = 180°

x = 180° - 100⁰

x = 80°

So, The value of x is 80⁰
