PLEASE HELP!! If the endpoints of have the coordinates A(9, 8) and B(-1, -2), what is the midpoint of ?

dimaraw [331]

M refers to midpoint.

$A(9, 8) \\B(-1, -2) \\M(\frac{x_1-x_2}{2}, \frac{y_1-y_2}{2}) \\M(\frac{9-(-1)}{2}, \frac{8-(-2)}{2}) \\M(\frac{10}{2}, \frac{10}{2})\Longrightarrow\boxed{M(5, 5)}$

Hope this helps.

The sides of AFGH are FG = 6x+7, GH = 8x - 5, and FH = 10x - 11. If the perimeter of FGH is 87, list the angles

liraira [26]

Answer:

<em>∠ H, ∠G, ∠F </em>

Step-by-step explanation:

6x + 7 + 8x - 5 + 10x - 11 = 87

24x = 96

x = 96 / 24 = 4

FG = 6(4) + 7 = 31 units

GH = 8(4) - 5 = 27 units

FH = 10(4) - 11 = 29 units

FG is the longest side ⇒ ∠H is the largest angle.

GH is the shortest side ⇒ ∠F is the smallest angle

<em>∠ H, ∠G, ∠F</em>
