Answer:
0.5
Step-by-step explanation:
we know , cos(90-α)=sinα
Given:sin(x)=0.5
So, cos(90-x)=sin(x)
=0.5
Therefore, cos(90-x)=0.5
The answer to this problem will be A. Plug in the numbers
Answer:
2 miles per hour
Step-by-step explanation:
We use the distance formula. D = r * t
45/3 = 15 mph | Trip 1 |
44/4= 11mph | Trip 2 |
15-11 = 4 mph difference traveling upstream or downstream. Thus the speed of the current is 2 miles per hour.
