A trigonometric ratio, abbreviated as sin. For a right triangle ABC, the sine of the acute angle A is
sin A =_length of leg opposite <A_ = _BC_ = _3_
length of hypotenuse AB 5
example: A chair on a ski slpoe has an angle of elevation of 28 and covers a total distance of 4640 feet. To the nearest foot, what is the vertical height h covered by the chair lift?
