C-09-Q037mediumsingle_mcqcotθ=adjacent?\cot\theta = \dfrac{\text{adjacent}}{?}cotθ=?adjacentaoppositebadjacentchypotenusedtangentব্যাখ্যাBy definition cotθ=adjacentopposite\cot\theta=\dfrac{\text{adjacent}}{\text{opposite}}cotθ=oppositeadjacent, the reciprocal of tanθ=oppositeadjacent\tan\theta=\dfrac{\text{opposite}}{\text{adjacent}}tanθ=adjacentopposite. Hence the denominator is the opposite side.
