Answer:

A: 24°

B: 22°

C: 134°

Step-by-step explanation:

A triangle will always add up to 180°

A + B + C = 180°

(2x + 4) + (2x + 2) + (13x + 4) = 180

2x + 2x + 13x + 4 + 2 + 4 = 180

17x + 10 = 180

17x = 180 - 10

17x = 170

17x/17 = 170/17

x = 10

A: 2x + 4

B: 2x + 2

C: 13x + 4

A: 24°

2x + 4

2(10) + 4

20 + 4

24°

B: 22°

2x + 2

2(10) + 2

20 + 2

22°

C: 134°

13x + 4

13(10) + 4

130 + 4

134°
