Fill in the missing angles if angle 1 is 125 degrees. Remember: vertical angles are equal and supplementary angles add to 180 degrees.

Answer:
See below
Step-by-step explanation:
Good work so far
1 = 4 so each are 125 degrees
We know that horizontal lines equal 180 degrees so:
125 + angle 3 = 180
180 - 125 = angle 3
angle 3 = 55
angle 3 = angle 2
so angle 2 is 55 as well
If we look at the angles below, they are the exact same as the angles above, therefore we can say that:
1 = 4 = 5 = 8
2 = 3 = 6 = 7
angle 6 and 7 = 55
