What here can be used to find the angle of depression or elevation with trig functions?
How about the sky?
Or the clouds?
*sigh* What about the trees?
I don't know, can they?
Oh my goodness. What about a slide?
FINALLY! IT'S ABOUT TIME!
You didn't even say the answer, I did!
Little Billy is on the slide and his friend is on the ground below. The length of the slide is 10 feet. The angle that the bottom of the slide forms is 75°. His friend wants to find out how high the top of the slide is from the ground. What do we do?
Why is Billy's friend worried about that anyway?
Manayah, we need you to focus.
Well, we know we are looking for the angle of elevation since we are trying to find the distance from the top of the slide to the ground.
So, we would use the trig function, sin because we would use the given length of the side that we do have, which is 10 feet, and substitute the length from the top of the slide to the ground for x, which would be be opp/hyp.
