1000 m = 1 km
5000 m = 5 km
They have traveled 5 km so far.
Subtract what they traveled from total distance:
24-5 = 19 km left.
Being able to do this problem hinges mainly on your knowing the definitions of the trig functions and being able to read side lengths from the given diagram.
csc theta = hypotenuse / opp side = 4 / √(4^2 + 5^2) = 4 / √41.
sin theta is the reciprocal of csc theta, or √41 / 4.
cot theta is adj side / opp side = 5/4.
Answer:
x = 3
Step-by-step explanation:
- Subtract 15 from each side, so it now looks like this: 21 = 7x
- Divide each side by 7 to cancel out the 7 next to x. It should now look like this: 3 = x
I hope this helps!
