s-28+s-17=s+22

s=22+28+17

s=67°

67°

Step-by-step explanation:

By remote exterior angle theorem of a triangle:

s - 28° + s - 17° = s + 22°

2s - 45° = s + 22°

2s - s = 45° + 22°

s = 67°

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)
