Find the midpoint of the line segment with the given endpoints. ( 1, -10),
(-7, 7).

The mid-point is basically the average of the coordinates. So for the x coordinate do (1+(-7))/2=-3. and for y, do (-10+7)/2=-3/2

This gives you the midpoint as (-3,-3/2)

hi friend

here is your answer

there are two angles that are alternate interior angle with angle 9

the angle 15 and angle 7 are alternate interior angle with angle 9.

hope it is for you so mark my answer as a brainliest

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.
