Question

HELP!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

79

Explanation:

m<1 = 90 -38 = 52

m<3 = 90 - 52 = 38\

m<2 = 180-38-63 = 79

Answer 2

Explanation:

<1 + <3 = 90 Parallel lines produce interior angles that add to to 90

<1 + 38 = 90 Substitution

<1 = 90 - 38 52

<3 = 90 - 52

<3 = 38

38 + 63 + <2 = 180 Sum of angles in a triangle always = 180

101 + <2 = 180

<2 = 79
