What is the distance Y Z in metres between the boat and the bouy, to 2 significant figures? - boat surveyors
An inspector who was standing on a vantage point on a cliff with a height of 300 meters, you can see a boat and a buoy at sea, both directly in front of him. Measuring the angle of the cliff, to the pin and 27-degree angle from the top of the cliff to Z boat 18 degrees.

Calculate the distance between the bottom of the cliff boasting buoy /:
The distance is 300/tan Boat (18) = 923.31m
Distance to the buoy is 300/tan (27) = 588.73m
Distance = 334.58m
Consider the cliff and the distance to a triangle, the angle occurring between the rocks and the sea itself. The distance from the cliff at the buoy would 300tan27. The distance from the cliff to the boat 300tan18. For this reason, because they are directly aligned with each other, the distance between them is not 300tan27-300tan18.
300 (* tan 27 tan18)
You should take some work.
SOH CAH TOA (The three reasons right triangle trigonometry), Tan (x) = opposite / adjacent
For this reason, in this case, tan (x) * = Next Front (Re-organization from the top)
Therefore, the distance of each object = 300 * tan (x)
Therefore, YZ = 300tan (z) - 300tan (y)
Therefore, YZ = 300 (tan (27)-N (18)) = 55,322 m seats (3 seats)
an image triangle.
then close the figures
can then use trigonometric functions to Z
I would like to solve them for you at the moment, but to go into IB 2 minutes for the next course. sorry
