Web\tan (L) = \dfrac {\text {opposite}} {\text {adjacent}} = \dfrac {35} {65} tan(L) = adjacentopposite = 6535 But this doesn't help us find the measure of \angle L ∠L. We're stuck! What we need: We need new mathematical tools to solve problems like these. Our old friends sine, cosine, and tangent aren’t up to the task. WebSin, cos, and tan functions in trigonometry are defined in terms of two of the three sides (opposite, adjacent, and hypotenuse) of a right-angled triangle. Here are the formulas of sin, cos, and tan. sin θ = Opposite/Hypotenuse cos θ = Adjacent/Hypotenuse tan θ = Opposite/Adjacent
