## anonymous one year ago Will give medal :) thanks :) Two buildings stand 90-ft apart at their closest points. At those points, the angle of depression from the top of the taller building to the top of the shorter building is 12 degrees. How much taller is the taller building? Round your answer to the nearest foot.

$90 \tan (12 {}^{\circ})=19$78 should be 12 .

@robtobey can you explain how you got 78 and 12 @.@

$\tan (12 {}^{\circ})=\frac{x}{90}$x = 19.1301 ft
