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
Answer:
A
Step-by-step explanation:
To express 4/5 as a decimal, you divide 4 by 5. Here is long division image at the bottom. You can just input it into a calculator (4 divdie 5) or notice that 4/5 = 8/10 = 0.8.
