The endpoints of segment TU are T(-8, 4) and U(6, -1). Calculate the coordinates of the midpoint, M. *

The point M(Mx, My) is mid-point of TU with T(Tx, Ty) and U(Ux, Uy).

=> 2*Mx = Tx + Ux => 2*Mx = -8 + 6 => Mx = -1

=> 2*My = Ty + Uy => 2*My = 4 + (-1) => My = 3/2

=> M(-1, 3/2)

Hope this helps!

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
