Answer:
A. 55°
B. 71°
C. 100°
D. 65°
E. 120°
F. 155°
G. 147°
H. 36°
I. 70°
J. 54°
K. 24°
L. 40°
Step-by-step explanation:
A. 180 - (90 + 35) = 55°
B. 180 - (34 + 75) = 71°
C. 180 - (43 + 38) = 100°
D. 180 - 50 = 130 / 2 = 65°
E. 180 - (90 + 30) = 60°
180 - 60 = 120°
F. 180 - (120 + 35) = 25°
180 - 25 = 155°
G. 180 - 145 = 35 + 112 = 148°
H. 180 - (40 + 26) = 144°
180 - 144 = 36°
I. 180 - (60 + 65) = 125°
180 - 125 = 55°
180 - (55 + 50) = 75°
180 - (75 + 35) = 70°
J. 180 - 116 = 64°
180 - (64 + 62) = 54°
K. 180 - (138 +18) = 24°
L. 180 - (80 + 60) = 40°
Answer:
The train ride is 3.5 hours
Step-by-step explanation:
We know that distance is equal to rate times time
d = rt
We know the distance and the rate
420 = 120*t
Divide each side by 120
420/120 = 120t/120
3.5 =t
The train ride is 3.5 hours
