\[\sin \frac{ opp }{ hyp }\]

Yes try using this here we know sin30=1/2

where did you get that from

sin30 is a standard angle...It is good to know value of sin 0,30,45,60,90 otherwise you can always use calculator :P

Now can you proceed from here?

eh no not really

basically the begining this confused me bc i was given the adjacent side to the angle

Sorry I couldn't understand you...can you explain more

timo86mBest ResponseYou've already chosen the best response.2
you use cos not sin if you are given adjecent. But better yet this problem requires tan :P

timo86mBest ResponseYou've already chosen the best response.2
tan because you are given the adjecent. And wanna know the oppossite side.

tan(30)=opp/adj=x/1000

highschoolmom2010Best ResponseYou've already chosen the best response.0
so i need to use tan

timo86mBest ResponseYou've already chosen the best response.2
Yup :D it is the simplest trig ID that has both opp and adj in it.

timo86mBest ResponseYou've already chosen the best response.2
tan(30)=opp/adj=x/1000 tan(30)=x/1000 solve for x can you do that?

highschoolmom2010Best ResponseYou've already chosen the best response.0
\[1000*\tan 30=\frac{ x }{ 1000 }*1000\] \[1000( \tan 30)=x\] but the angle is 32 degrees

timo86mBest ResponseYou've already chosen the best response.2
1000*tan 32 =x is right so far :D what you do now is evaluate tan 32 in degree mode SOrry at typo

i must have look at that other guy who say sin 30 lol.

1000 tan (32) gave me a crazy answer
 8 months ago

timo86mBest ResponseYou've already chosen the best response.2
1000*(tan 32) =x ok so we got this far all we do is use our calculator making sure we in degree mode not radian mode tan32=0.62486935190932750978051082794943665831087020284270496 so we jsut plug that in 1000*.6248=624.8 ft sounds believeable. ooh plus 6 feet for the guys height at eye level 624.8+6

so rock climber is approx. 630.8' from the ground

timo86mBest ResponseYou've already chosen the best response.2
if that is one of your answer choices :D use the one that is closest to our answer. oh and i would go with that lol.
