Question

In the figure below, line l is parallel to line m, line CD bisects angle ACE, and angle 1 = 130. Find the measure of each angle.

Answer 1

please help, i don't know how to find angles 7,8,4, and 65

Answer 2

i mean 5

Answer 3

please don't go away. I really need help on it and my teacher will refuse to help me

Answer 4

have you found the rest of them?

Answer 5

5=80°

Answer 6

because m<6+m<5=130 (because 5+6 = 1 due to alternate exterior angles are congruent)

and I assume you found that m<6=50 because m<6=m<3 (vertical angles congruent) and m<3 = m<2 (alternate interior angles)

so m<5 = 130-50 = 80

Answer 7

this is what i got for all the angles:
1= 130
2 = 50
3 = 50
4 = 50
5 = 80
6 = 50
7 = 50
8 = 80
9 = 50
10 = 50
11 = 80
12 = 80
13 = 100
14 = 100
15 = 80
