Answer:
The magnitude of the resultant force is:

The direction is:

Step-by-step explanation:
Let's find the components of each vector is x and y-directions first.
<u>Sum of x-component vector forces.</u>



<u>Sum of y-component vector forces.</u>


The magnitude of the resultant force is:


The direction is:



I hope it helps you!
X equals 3 because i know 2 to the fifth power is 32,so 3x-4=5so 3*3=9
Let s be the speed of the boat in still water.
Let c be the speed of the current.
s - c = 48/6 = 8
s + c = 48/4 = 12
Adding the two equations, we get:
2s = 20
s = 10
The answer is 10 miles per hour.
