Answer:
4.55 mi N70°E, or 4.6 mi n70°E
Step-by-step explanation:
Draw a diagram; it helps keep the trig functions straight.
Starting from (0,0) a walk of 2 mi at N40°E leaves him at
x = 2sin40° = 1.29
y = 2cos40° = 1.53
Now, a walk 3 mi due east leaves him at
(4.29,1.53)
The new bearing is an angle θ with tanθ = 4.29/1.53 = 2.80
so, the new location is 4.55 mi N70°E
Already you can see that -y and y will make a zero
add both together
3x=21
x=7
plug x in
7+y=5
y=-2
