Answer:
[tex]c = 7.6157731059mi[/tex]
[tex]c \approx7.6mi[/tex]
Step-by-step explanation:
[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]
[tex]c = \sqrt{ {a}^{2} + {b}^{2} } [/tex]
[tex]c = \sqrt{ {3}^{2} + {7}^{2} } [/tex]
[tex]c = \sqrt{9 + 49} [/tex]
[tex]c = \sqrt{58} [/tex]
[tex]c = 7.6157731059mi[/tex]
[tex]c \approx7.6mi[/tex]
