Can somebody please solve this for me?

x= 121

y = 93

Step-by-step explanation:

90+x+x-28 = 180(linear pair)

or, 2x-62 = 180

or, 2x = 242

so, x = 121

now

y = x-28(veritically opposite)

or, y = 121 - 28

so, y = 93

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)
