Triangle ABC is a right triangle. Which equations can be used to find the value of x? Check all that apply.
X+90+ (x-10) - 180
X+90+ (2x+40) = 180
2x+80 = 180
x+90 = 2x+40
(x-10)+90 = 2x+40

A) X+90+ (x-10) - 180

C) 2x+80 = 180

D) x+90 = 2x+40

I just took the quiz on edge

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
