Answer 1

Answer:

m∠4 = 80°

Explanation:

m∠7 = 100°

and since m∠7 = 100°, m∠3 = 100° (corresponding angles of congruency)
and m∠3 can also equal to m∠1 (opposite side)

so…

m∠7, m∠3, m∠1 must equal to 100°

oh also m∠5

so to find the m∠4, subtract 180° - 100°

m∠4 = 80°

Answer 2

80 degrees

Explanation:

Hi there!

The angle that measures 100 degrees and angle 8 are supplementary, meaning they add up to 180 degrees.

180 - 100 = Angle 8

Angle 8 = 80 degrees

Therefore, angle 8 measures 80 degrees.

Now, angle 4 and angle 8 are corresponding angles. This makes them equal.

Therefore, angle 4 is 80 degrees.

I hope this helps!
