Answer:
24.4 km
Explanation:
The Pythagorean theorem states that a^2 + b^2 = c^2, where c is the hypotenuse of the triangle, and a and b are the legs. Plugging in your values, we get:
20^2 + 14^2 = c^2
Simplify: 400 + 196 = c^2
Simplify again: 596 = c^2
Square root both sides to cancel out the exponent on the right: 24.4131=c
Round: 24.4
