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

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

answer: 48
