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)
Also dont really understand what a secant is

Answer 1

In geometry, a secant line of a curve is a line that\ intersects two points on the curve. A chord is an interval of a secant line, the portion of the line that lies within the curve.

Answer 2

when you know hypotenuse and another side thats opposite to missing angle in a right triangle, you can use 'sin' or 'co-secant' ratios :-

sin = opposite/hypotenuse

co-secant = 1/sin

so, there is no difference. co-secant is just reciprocal of sin. you can use either of them. However you will end up using sine ratio most of the time, as most calculators allow u to get the inverse sin easily without changing settings.

Answer 3

Ok , so I know that sin = opposite/hypotenuse co-secant = 1/sin, but what about with cosine
