Question

If m∠2 = 130°, find m∠5.

Answer 1

m∠5= 50°

Explanation:

The line for m∠1 and m∠2 adds up to 180°

So if m∠2 = 130° then subtract 130 from 180 which would equal 50.

and m∠1 is parallel to m∠5 which is why it equals to 50°

Answer 2

50

Explanation:

Angle 2 is the same as angle 6. If you add angle 6 and angle 5 to get 180, then if you do 180 minus 130, because angles 2 and 6 are the same, then it equals 50.
