Answer:
301.42 ft from base
Step-by-step explanation:
We can look at this situation as a triangle, the cliff is straight up and we're looking for the lowest side of the triangle. So to figure this out we use tangent, tangent is equal to Opposite over adjacent. So the tangent(37)= bear from base/height of cliff. We then multiply tan(37) by 400 to get the answer
Answer:
parallel
a quadrilateral can be a parallelogram only and only if pair of opposite sides are equal and parallel.
Answer:
Step-by-step explanation:
- Speed of the boat = x
- Speed of the current = y
<u>Travel downstream, speed is:</u>
<u>Travel upstream, speed is:</u>
<u>Add up the equations:</u>
- x + y + x - y = 30 + 20
- 2x = 50
- x = 25
<u>Find y:</u>
Speed of the boat is 25 mph
Speed of the current is 5 mph
