Answer:
D
Step-by-step explanation:
(4,-3) lies in the fourth quadrant where cos is positive
cos(θ) = adjacent/hypotenuse
hypotenuse² = 4² + 3² = 25
Hypotenuse = 5
cos(θ) = 4/5
-3/4
cos theta = (adjacent /hypothesis) =(-3/4)
there is nothing ?
i dont know
Try 12.5, hopefully this helps :)
Carry the decimals the same places to make the number you are dividing by whole and give the number you are dividing by the extra decimal places. then divide.
I hope that makes sense :/
