Answer:

Step-by-step explanation:

10.

m<1 = 53°

m<2 = 53°

m<3 = 68°

m<4 = 59°

m<5 = 121°

11.

m<1 = 62°

m<2 = 23°

m<3 = 157°

m<4 = 29°

m<5 = 62°

12.

7x + 4 = 10x - 11

4 + 11 = 10x - 7x

15 = 3x

15/3 = x

5 = x

13.

5x + 2 + 11x - 30 = 180°

16x - 28 = 180

16x = 180 + 28

x = 208/16

x = 13

14.

9x + 2 = 15x - 52

54 = 6x

54/6 = x

9 = x

---------------------

<CBF = (9x + 2)

9 (9) + 2 = 83°

15.

6x + 1 + x + 4 = 180°

7x + 5 = 180

7x = 175

x = 175/7

x = 25

---------------------

<RTV = x + 4

25 + 4 = 29°

hope this helps you
