Question

MEDAL AND FAV! Im having problems seeing a trigometric ratio!

The figure shows a right triangle:

A right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units. The angle between the legs having lengths p units and q units is y degrees. The angle between the legs having lengths r units and q units is x degrees.

What is r ÷ q equal to?

sin x°

cos y°

cos x°

tan y°

Answer 1

by definition

cosine = adjacent/hypotenuse

cos(x) = adjacent/hypotenuse ... notice how angle x is adjacent to r

cos(x) = r/q


also,

sine = opposite/hypotenuse

sin(y) = opposite/hypotenuse ... notice how angle y is opposite side r

sin(y) = r/q

Answer 2

so it would be C correct?

Answer 3

correct
