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°
