39 loser123456789 0A slide 4.1 meters long makes an angle of 35° with the ground. To the nearest tenth of a meter, how far above the ground is the top of the slide?

cos?

4. valentinekid

well x is opposite our angle and we know the hypotenuse...

5. loser123456789

sin

6. valentinekid

Exactly. Any guess as to how to setup the problem from there? sin(angle)=opp/hyp

7. loser123456789

sin(35)=x/4.1

8. valentinekid

BOOM! You got this! haha now just isolate x by multiplying both sides by what?

9. loser123456789

x/1

10. valentinekid

Let's multiply both sides by 4.1 and see what happens.

11. loser123456789

4.1*sin(35)=x

12. valentinekid

That's all there is to it. Trig isn't so bad, is it? ;)

13. loser123456789

is that the final answer or is there more simplifying

14. valentinekid

That's it. Remember though if you're asked to give an actual number instead of 4.1*cos(35) plug it in to your calculator.

15. loser123456789

thank you so much

16. valentinekid

Yeah, no worries! Best of luck. :)
