Question

What is m∠2?
What is m∠1?

Answer 1

75

105

Explanation:

Answer 2

<2 = 75

<1 = 105

Explanation:

<2 and 75 are alternate interior angles and since the lines are parallel, they are equal

<2 = 75

<2 + <1 = 180 since the angles form a line

75+ <1 = 180

Subtract 75 from each side

<1 = 180-75

<1 = 105
