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?

Answer 2

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

Answer 3

cos?

Answer 4

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

Answer 5

sin

Answer 6

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

Answer 7

sin(35)=x/4.1

Answer 8

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

Answer 9

x/1

Answer 10

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

Answer 11

4.1*sin(35)=x

Answer 12

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

Answer 13

is that the final answer or is there more simplifying

Answer 14

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.

Answer 15

thank you so much

Answer 16

Yeah, no worries! Best of luck. :)
