Answer:

See below for answers and explanations

Explanation:

Given P(-3,4) we can solve for the third side:

c=√[(-3)²+4²]

c=5

If the terminal side of ø in standard position contains the given point, then it is located at that point, making -3 the opposite side (the side length is 3), 4 the adjacent side, and 5 the hypotenuse.

Therefore:

cos∅=adjacent/hypotenuse=4/5

sin∅=opposite/hypotenuse=3/5

tan∅=opposite/adjacent=3/4
