Daily Regents:Trigonometric Ratios (June 2015)

I'll be reviewing a New York State Regents Exam Question every day from now until the Regents exams next week. At least, that is the plan.

Geometry, June 2015, Questions 28

27. The diagram below shows a ramp connecting the ground to a loading platform 4.5 feet above the ground. The ramp measures 11.75 feet from the ground to the top of the loading platform.

Determine and state, to the nearest degree, the angle of elevation formed by the ramp and the ground.

A trigonometric ratio problem. The height of the platform is opposite the angle. The ramp is the hypotenuse. This means we have the sine ratio for the angle.

sin x = (4.5 / 11.75)

Any questions?
