First, find the length of the hypotenuse using the Pythagorean theorem: a^2+b^2=c^2
25 + 144 = c^2
= c^2
13 = c
Now, find each of the values! Sin = opposite/hypotenuse; Cos = Adjacent/hypotenuse; Tan = Opposite/Adjacent.
1. A

Answer:
( -8, -4)
Step-by-step explanation:
Think of the graph as 4 different sections,
top left is 1
top right is 2
bottom right is 3
bottom left is 4
The red dot is (4, -8) and the blue dot is ( -8, -4 )
If you move from the right side of the grid to the left you would switch (x ,y ) to (y , x).
depending on what part of the graph it is in, it will be negative or positive.
hope this helps!
