Find the value of x then find the measure of each labeled angle

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
