In a right triangle, the sine of an angle is 0.854. what is the cosine of the same angle? there are two possible answers, one positive and one negative. enter the positive value as your answer.

step-by-step explanation:

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
