Best ResponseYou've already chosen the best response.1x is the angle O = opposite side H = hypotenuse (longest side) A = adjacent side sin x = O / H cos x = A / H tan x = O / A

Best ResponseYou've already chosen the best response.1in your problem you know one angles 24.7 degrees and you know the adjacent side 140 and you need to find the opposite side x = 24.7, A = 140 and O = ? so you have O and A (TOA) so u need to use the tangent (T) tan 27.4 = x / 140 so x = 140* tan 24.7 grab your calculator and you can work this out
