Write each trigonometric ratio as a fraction in simplest form. show all supporting work

Step-by-step explanation:

Sine uses the ratio,   so we can plug in the information we know. since there is no current value for the opposite side of angle A, we can just use a variable to replace it.

You can't reduce this any further because there is an unknown variable.

step-by-step explanation:

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
