From a boat on the water, the angle of elevation of the drop of a cliff is 31°. From a point 300 m closer, the angle of elevation is 33°. Find the height of the cliff.
the answer should be 2411 m.
I had tan31° = h/x+(x-300)
tan33° = h/x-300 -> (x-300)tan33° = h.
I subbed the first one into the second:
tan31° = (x-300)tan33°/x+x-300
I'm not sure how to go from there or if what I have so far is even right.
Math (trigonometry) -
From the top* of a cliff, not from the drop of a cliff.
