Answer: 707 km/h
Step-by-step explanation:
let c = speed of current
16.5 + c = speed of sailboat downstream
16.5 - c = speed of sailboat upstream
distance = travel time * speed
﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋
2(16.5 + c) = 5(16.5 - c)
33 + 2c = 82.5 - 5c
7c = 49.5
c = 7.07 km/h
Answer:
120 ? what this supposed to be about ? is it to estimate or subtract? does this have mutiple choices? and what gum are their referring too ? the gum you chew or in your teeth?

Answer:
Step-by-step explanation:
By definition, the tangent of an angle is the quotient between the side opposite the angle and the side adjacent to the angle
In other words:
In this triangle, the length of the side adjacent to the desired angle is 50, and the length of the opposite side is 48
So:
Finally
