Please look at the attached image to answer the question.

Answer for 1st set:

m∠1=105° and m∠2=75°

Breakdown:

You're given one angle of 75°. That one angle is equal to m∠2. Since m∠2 is making a linear pair with m∠1, you take 180° (Straight line) and take 75° from it.

180-75=105

Answer for 2nd set:

m∠1=130° and m∠2=50°

Breakdown:

Using the same logic as before, linear pair, blah-blah-blah, you're given 130.

180-130=50

m∠1=105° and m∠2=75°
