Find cos x if sin x cot x = 0.5. - Brainly.com
2019年3月5日 · Given the equation sinxcotx = 0.5, we find that cosx = 0.5. This corresponds to the angles 60° (or 3π) and 300° (or 35π). Choice A is correct. sin x cot x = 0.5. We have to find the value of cos x . As we know that cot x is the ratio of cos x and sin x. cot x = cos x / sin x. sin x (cos x / sin x) = 0.5. cos x = 0.5 is the answer.
