Question

Given: a||b, and c||d, m∠4=45°
Find: the measures of angles 1, 2, and 3

Answer 1

<2=45 degrees

Explanation:

Answer 2

m<1=135 degrees, m<2=45 degrees and m<3=135 degrees

Explanation:

m<4 and m<2 are parallel lines so m<2 is 45 degrees and 180-35=135 so we found out that m<3 is 135 degrees and m<3 and m<1 are parallel so m<1 is 135 degrees too. So this is the answer.
