Sintheta = opp/hyp

OpenStudy (anonymous):

Can you help me more ?

OpenStudy (anonymous):

so you have the opp side right?

OpenStudy (anonymous):

Yes, 9

OpenStudy (anonymous):

alright and you have the angle and now you also have the trig function.

OpenStudy (anonymous):

What are you looking for?

OpenStudy (anonymous):

x

OpenStudy (anonymous):

Yes but what side is it of the triangle?

OpenStudy (anonymous):

hypotenuse

OpenStudy (anonymous):

yup ok so I shouldn't have told you the function right away since it gives it away but its fine lol. We know that sintheta = opp/hyp now use this algebraically to find the hyp.

OpenStudy (anonymous):

9/x

OpenStudy (anonymous):

Yes but what do you do with the sintheta and the angle :)

OpenStudy (anonymous):

I don't know haha

OpenStudy (anonymous):

alright so you know that sintheta = opp/hype right, now you just do it algebraically => hyp = opp/sintheta where theta = angle, now you just need to plug in the numbers, don't over think this too much, it's not as bad as you think it is.

sin 39 = 9/x 0.6923x = 9 x = 13

OpenStudy (anonymous):

14.3 ;d

OpenStudy (shamil98):

no, check your sin value ..

OpenStudy (anonymous):

I used wolfram haha so it must be correct.

OpenStudy (anonymous):

I'll use my calculator though..

OpenStudy (anonymous):

It's 14.301...

OpenStudy (shamil98):

sin 39 = 0.6923 -.-

OpenStudy (shamil98):

0.6293*

OpenStudy (anonymous):

That's because you're just using 4 digits lol

OpenStudy (anonymous):

You're final answer is 14.3. Just make sure you understand the concept.

OpenStudy (anonymous):

Thank you (:
