Angle of Elevation A woman entering an outside glass elevator on the ground floorof a hotel glances up to the top of the building across the street and notices that theangle of elevation is 48 degree . She rides the elevator up three floors (60 feet) and finds thatthe angle of elevation to the top of the building across the street is 328. How tall is thebuilding across the street? (Round to the nearest foot.)
Ratios
A ratio is a comparison between two numbers of the same kind. It represents how many times one number contains another. It also represents how small or large one number is compared to the other.
Trigonometric Ratios
