Best ResponseYou've already chosen the best response.0we'll handle this the same way... SOHCAHTOA go to the angle corner, and figure out given sides as opposite,adjacent and hyp

Best ResponseYou've already chosen the best response.1Use tangent here. Tanx = opposite/adjacent. What side is opposite angle x? dw:1376249499008:dw \[\Large \tan x = \frac{ \text{opposite} }{\text{adjacent} }\]

Best ResponseYou've already chosen the best response.1\[\tan(x)=\frac{ 8 }{ 5 }\] \[(5)*\tan x=\frac{ 8 }{ 5 }*(5)\]

Best ResponseYou've already chosen the best response.0nopes ! leave it as it is tanx = 8/5

Best ResponseYou've already chosen the best response.0yes ! just divide the right side, then take inverse tan both sides

Best ResponseYou've already chosen the best response.1No need for extra work here :P \[\tan(x)=\frac{ 8 }{ 5 }\] so \[x = \tan^{1} \frac{ 8 }{ 5 }\]which you need a calculator for.

Best ResponseYou've already chosen the best response.0see, you have tan x = 8/5

Best ResponseYou've already chosen the best response.0you want to find x, so to find x you have to isolate x

Best ResponseYou've already chosen the best response.1tan^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.

Best ResponseYou've already chosen the best response.0take tan^1 both sides : tan x = 8/5 tan^1 tan x = tan^1 8/5 x = tan^1 8/5

Best ResponseYou've already chosen the best response.1If 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.
