we'll handle this the same way... SOHCAHTOA go to the angle corner, and figure out given sides as opposite,adjacent and hyp

Use tangent here. Tanx = opposite/adjacent. What side is opposite angle x? dw:1376249499008:dw \[\Large \tan x = \frac{ \text{opposite} }{\text{adjacent} }\]

Hypotenuse we don't need, use tanx = opp/adj.

That's a good tactic, especially for subjects like physics :)

\[\tan(x)=\frac{ 8 }{ 5 }\] \[(5)*\tan x=\frac{ 8 }{ 5 }*(5)\]

nopes ! leave it as it is tanx = 8/5

yes ! just divide the right side, then take inverse tan both sides

No need for extra work here :P \[\tan(x)=\frac{ 8 }{ 5 }\] so \[x = \tan^{1} \frac{ 8 }{ 5 }\]which you need a calculator for.

so when finding angles like ^^ use tan^1

see, you have tan x = 8/5

you want to find x, so to find x you have to isolate x

tan^1 is the "opposite" of tan, so you use it to undo it. Just like a square root is the opposite of squared, a square root undoes the squard.

take tan^1 both sides : tan x = 8/5 tan^1 tan x = tan^1 8/5 x = tan^1 8/5

TY soo much @agent0smith && @ganeshie8

If you have sinx = some number, then you'd use sin^1(some number) to undo it. Same for cosx = some number. But make sure you isolate the sinx or cosx, so it's like sinx = ... or cosx = ... ie you can't just do cos^1 of 10cosx = 5, you'd have to divide by 10 first.
