answer:
c = 7.6 kilometers
step-by-step explanation:
- you can use the pythagorean theorem for this since this is a right triangle
- know the formula: a^2 + b^2 = c^2
now plug in what we know, also remember:
- a = leg
- b = the other leg
- c = hypotenuse
a^2 + b^2 = c^2
3^2 + 7^2 = c^2
9 + 49 = c^2
58 = c^2
c = 7.6157
rounded: c = 7.6 kilometers
