As shown in the model below, there are three lines.
Answer:
114
Step-by-step explanation:
since the total degrees of ANY triangle is 180 degrees, you just simply do 180-38-28 and you would get 114!
Answer: a) 490.91 mph
b) 540 mph
c) speed of the wind = 49.1 mph
Step-by-step explanation:
Given that flight between Joppetown and Jawsburgh took 5 hours and 30 minutes.
Time t = 5.5hours
Distance = 2700 miles
Speed = distance/ time
Speed = 2700/5.5
Speed = 490.91 mph
The return flight took 5 hours of the same distance from = 2700 miles
Speed = 2700/5 = 540 mph
speed of the wind = the difference in the two speed
speed of the wind = 450 - 490.91
speed of the wind = 49.1 mph
Speed = 540m/s
In order for the system to have an infinite number of solutions, both equations must be identical. So, the value of b must be 6
