Web$\begingroup$ yes, sine=opp/hyp, cos=adj/hyp and tan=opp/adj. sin=3/√15 rationalized to be √15/5 cos=2/√15 rationalized to be 2√15/15 and tan =3/2 or 1.5 I guess am confused by the little curvy arrow in the picture that refers to angle a. I thought i had to find the angle? So bascially if you can confirm that I did this all correct and not need to find the angle then I … WebThe adjacent side (\ (a\)) is next to the angle in question (\ (x\)).

WebFor one specific angle a, e.g. a = 30° the three basic trigonometry functions – Sine, Cosine and Tangent, are ratios between the lengths of two of the three sides: Sine: sin (a) = Opposite / Hypotenuse. Cosine: cos (a) = Adjacent / Hypotenuse. Tangent: tan (a) = Opposite / Adjacent. That is all good when angle a is between 0° and 90°. WebThe important sin cos tan formulas (with respect to the above figure) are: sin A = Opposite side/Hypotenuse = BC/AB. cos A = Adjacent side/Hypotenuse = AC/AB. tan A = Opposite side/Adjacent side = BC/AC. We can derive some other sin cos tan formulas using these definitions of sin, cos, and tan functions. We know that sin, cos, and tan are the ...
