Please help me with Missing lengths in trigonometry!!! :(

OpenStudy (elisaneedshelp):

22 and 24 please or mayb if you teacher me 22 i can do 24 by myself

OpenStudy (elisaneedshelp):

@luvalpaca i know you are there

OpenStudy (anonymous):

oh gosh lil momma wish i could help im not a mathie imma player LOL jk

OpenStudy (elisaneedshelp):

Lol i need a mathie dude im not interested in anything else

OpenStudy (ipwnbunnies):

Dude tryna get girls on a homework site lol. Go outside.

OpenStudy (jdoe0001):

hmm

OpenStudy (elisaneedshelp):

Ikr ^ and the guys that messaged me i didnt even reply

OpenStudy (elisaneedshelp):

Some1 help meee and dont give up on me even tho you lose your patience

OpenStudy (ipwnbunnies):

Ok, for 22, it gives us plenty to figure out the remaning 2 sides

OpenStudy (ipwnbunnies):

Do you remember what the sin of an angle is, in terms of its sides?

OpenStudy (elisaneedshelp):

sin is opp/hyp

OpenStudy (jdoe0001):

http://openstudy.com/updates/5324c8b6e4b0ba8d4c40e139 <--- did you ever get the value for \(\square\quad ?\)

zepdrix (zepdrix):

That should help with 30/60/90 triangle.

OpenStudy (elisaneedshelp):

nope i was confused my that too @jdoe0001

OpenStudy (jdoe0001):

hmm well.. \(\bf \square \sqrt{3}={\color{blue}{ 9}} = ? \)

OpenStudy (ipwnbunnies):

Alright good. So it gives us angle 60 degrees. sin(60) = opposite/hypotenuse. They gave us the "opposite" side, so we just solve for hypotenuse. hypotenuse = 9/sin(60). And you can figure out the sin of 60 degrees by the special triangles jdoe has above.

OpenStudy (jdoe0001):

\(\bf \square \sqrt{3}={\color{blue}{ 9}}\implies \square =\cfrac{{\color{blue}{ 9}}}{\sqrt{3}} \\ \quad \\ simplified\implies \cfrac{9}{\sqrt{3}}\cdot \cfrac{\sqrt{3}}{\sqrt{3}}\implies \cfrac{9\sqrt{3}}{\sqrt{3^2}}\implies \cfrac{\cancel{9}\sqrt{3}}{\cancel{3}}\implies 3\sqrt{3}\)

really? i wouldnt cheat on my gf dude ur not cool

OpenStudy (elisaneedshelp):

neither would i cheat on my bf

zepdrix (zepdrix):

...

OpenStudy (anonymous):

i said i was kidding she new that too

OpenStudy (jdoe0001):

so you see what \(\square\) is ? so use that for the other sides in the triangle, as shown by zepdrix

OpenStudy (elisaneedshelp):

wait so 3sqrt3 isnt supposed to become a whole number or something?
