Question

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.

Answer 1

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.

Thank you! :)
