Best ResponseYou've already chosen the best response.3I must correct it to '\(\sin\) of an angle'.

Best ResponseYou've already chosen the best response.3You find the opposite side of that angle, and then divide that by the hypotenuse in the given triangle.

Best ResponseYou've already chosen the best response.3And that, ma'am, is the way to find \(\sin\) given an angle.

Best ResponseYou've already chosen the best response.3Actually, 72 is not opposite to V. dw:1343316700534:dw

Best ResponseYou've already chosen the best response.3Also, hypotenuse is the longest side. Note that the thing I told you applies only for right triangles.

Best ResponseYou've already chosen the best response.1This is a useful mnemonic to remember fundamental trigonometric concepts. Classic: SOH CAH TAO Sin = Opposite side length / Hypotenuse side length Cosine = Adjacent side length / Hypotenuse side length Tangent = Opposite side length / Adjacent side length

Best ResponseYou've already chosen the best response.3Erm, it's SOH CAH TOA @dpflan

Best ResponseYou've already chosen the best response.1so would cosX be 72/75

Best ResponseYou've already chosen the best response.3Um, no. \[\cos = {{\text{adjacent} \over \text{hypotenuse}} \Longrightarrow \cos X = ? } \]

Best ResponseYou've already chosen the best response.3Adjacent side is \(21\). Hypotenuse is the longest side i.e \(75\).

Best ResponseYou've already chosen the best response.1OK AND TAN X WOULD BE 21/72

Best ResponseYou've already chosen the best response.0Some people have curly brown hair,they paint black some=sine people have=perpendicular(from people)/hypatenus(from have) so sine=perpendicular/hypatanus curly=cosine brown hair=base(from brown)/hypataneus(from hair) so cosine=base/hypatenus they=tan paint black=perpendicular(from paint)/base(from black) so tan=perpendicular/base whole trignometry in just in line!!!!!!!!!! hahahahaahaha @cerichards
