Answer:
LM = 15 units
Step-by-step explanation:
Vertices of ΔLMN are,
L(9,7), M(9, -8), N(1,7)
By using formula to get the distance between two points [tex](x_{1},y_{1})[/tex] and [tex](x_2, y_2)[/tex],
Distance = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
Therefore the distance between vertices L and M:
LM = [tex]\sqrt{(9 - 9)^2 + (7 + 8)^2}[/tex]
LM = 15 units
