You have an angle of elevation of 3 degrees and you're 2000 ft from base of 30 story building.
Draw a picture of this. Then tan(3) = ht of bldg/2000
I get a height of 104.82 ft rounded to 2 dp.


5. Ok. use the Pythagorean Theorem here to find the hypotenuse of the right triangle
hypt = sqrt(50^2 + 9^2)
Now sine of the angle of elevation is 50/hypt. = 0.984 or 0.98 to 2 dp.
