Answer:
The mid-point is (9,-9/2)
Step-by-step explanation:
You would use the mid-point formula for this
if you plug that in it is (
)
resulting in (11/2,-2/2) = (11/2,-1)
To solve for the last side of the triangle, use the Pythagorean Theorem:
(8)^2 + x^2 = (9)^2
x = sqrt of 17
However, this is a NEGATIVE sqrt 17 because the terminal side is in quadrant 4, meaning that this side is under the X-axis and therefore negative.
Now that you know the side opposite of u in the triangle, do opposite/hypotenuse.
sin u = -(sqrt 17)/9
