Question 927635: How tall is a building that casts a 65-ft shadow when the angle of elevation of the sun is 35 degrees? (simplify your answer. Type an integer or a decimal. Round to the nearest hundredth if needed.
I used tan (35 degrees)= OPP / 65
my answer : 45.51
But my online homework says it's wrong, i'm not sure what it is that i am doing wrong.

Think of the arrangement like a triangle with bottom being 65 feet for the shadow, and you want the vertical length. The angle 35 degrees lets you say, y%2F65=tan%2835%29, same format as what you have.

y=65%2Atan%2835%29
highlight%28y=45.51%29 feet
