Step-by-step explanation:

[tex] ({Perpendicular})^{2} + ({Base})^{2} = ({Hypotenuse})^{2} \\ ➪\:( {36 \: km})^{2} + ({27 \: km})^{2} = {c}^{2} \\ ➪ \: {c}^{2} = 1296 \: {km}^{2} + 729 \: {km}^{2} \\ ➪ \: {c}^{2} = 2025 \: {km}^{2} \\ ➪ \: c \: = \sqrt{ {2025 \: km}^{2} } \\ ➪ \: c \: = 45 \: km[/tex]
