Question

Lines I and m are parallel. Find m<3 if m<5 = 38 and m<6 = 62.

100

62

80

38

Answer 1

Answer: 80 degrees ==> 3rd option

Explanation:

m<5=m<2 ==> angles 5 and 2 are opposite interior angles, so they're congruent.

m<2=38 degrees

m<2+m<6+m<3=180 degrees

38+62+m<3=180

100+m<3=180

m<3=80 degrees ==> 3rd option
