Explain the difference between using the cosine ratio to solve for a missing angle in a right triangle versus using the secant ratio. You must use complete sentences and any evidence needed (such as an example) to prove your point of view. (10 points)

Correct   cosine α · secant α = 1

Step-by-step explanation:

I will give you definitions of the trigonometric functions of cosine and secant in a right triangle.

The cosine of an angle of a right triangle (which is not right) is the quotient of  the cathetus and the hypotenuse that build that angle.

cosine α = b / c

The secant of an angle of a right triangle (which is not right) is the quotient of  the hypotenuse and the cathetus that build that angle.

secant α = c / b

Their relationship is:

cosine α · secant α = 1  or cosine α = 1 / secant α or

secant α = 1 / cosine α

God is with you!!!
