How do i find the value of each variable? ?

Isosceles, so

6y - 2 = 4x + 20

4x - 6y = -22

Also, the angles add to 180 degrees,

52 + (6y - 2) + (4x + 20) = 180

4x + 6y = 180 - 52 + 2 - 20 = 110

Adding

8x = 88

x = 11

6y = 110 - 4 x = 110 - 44 = 66

y = 11

x=11, y=11

-6 is the correct option from the above given options

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)
