A slide 5.7 meters long makes an angle of thirty-two degrees with the ground. How high is the top of the slide above the ground? I'm having a hard time solving this. I don't know what to do with it.

OpenStudy (anonymous):

did you draw the picture? You can construct a right triangle with hypotenuse 5.7 meters and angle of elevation 32 degrees. sin=O/H. sin(32)=height/5.7. 5.7*sin(32) is your height.

OpenStudy (anonymous):

make sure the calculator is in degree mode

OpenStudy (anonymous):

Degree mode?

OpenStudy (anonymous):

yes some calculators have different modes for angles in radians and angles in degrees

OpenStudy (anonymous):

does the solution make sense?

OpenStudy (anonymous):

No, it's none of the options that I'm given.

OpenStudy (anonymous):

let me type it in real quick.

OpenStudy (anonymous):

i get 3.02 m

OpenStudy (anonymous):

that's not a choice?

OpenStudy (anonymous):

No, I have 1.42 m, 1.55 m, 2.45 m, and 1.36 m. This problem is really confusing.

OpenStudy (anonymous):

the angle between the ground and the slide is 32 degrees and the slide is 5.7 meters long?

OpenStudy (anonymous):

if that's correct the height is 5.7sin(32)

OpenStudy (anonymous):

Hmmm. I'm having a talk with my teacher tomorrow.
