I'm pretty sure you just add all the numbers up so it would be 569.9 ft
55x5 - 40x5
The third one down
You have an angle of elevation of 3 degrees and you're 2000 ft from base of 30 story building.
<span>Draw a picture of this. Then tan(3) = ht of bldg/2000 </span>
<span>I get a height of 104.82 ft rounded to 2 dp. </span>
<span>5. Ok. use the Pythagorean Theorem here to find the hypotenuse of the right triangle </span>
<span>hypt = sqrt(50^2 + 9^2) </span>
<span>Now sine of the angle of elevation is 50/hypt. = 0.984 or 0.98 to 2 dp.</span>
The answer is 3.5 + 1.5x = 12.5. So the answer would be C.
