Answer:
The resultant speed is 294.5 mi/h in a direction N79.7°E
Step-by-step explanation:
Let
East and North as the positive x and y-axis, respectively.
West and South as the negative x- and y-axis, respectively.
I'm pretty sure you are asking for the value of b. Let's actually write it and then solve it:
Solving for b yields:
So,
b = 19.59. If you want the answer in simplified radical form, we can also do that:
So,
b = 8√6 = 19.59
Answer:
d = 5,35 ft
Step-by-step explanation: See annex
Figure in annex is clear,
sin ∠42⁰ = d / 8
And
sin ∠42⁰ = 0.669
d/8 = 0,669
d = 0,669*8
d = 5,35 ft
