    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?

    So which Trig function should we use? Remember Sin=opposite/hypotenuse cos=adjacent/hypotenuse tan=opposite/adjacent

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

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

    sin(35)=x/4.1

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

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

    4.1*sin(35)=x

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

    is that the final answer or is there more simplifying

    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.
