Line l is parallel to line m. If the measure of <6 is 75°, what is the measure of <3?

∠3 = 105

Step-by-step explanation:

∠6 and ∠3 are consecutive interior angles, therefore they are supplementary

∠6 + ∠3 = 180

75 + ∠3 = 180

-75              -75

∠3 = 105

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
