Find the length of the missing side. round answers to the nearest tenth (one decimal). right triangle with base=6.3 mi and hypotenuse=15.4 mi

14.1 mi

Step-by-step explanation:

Use pythagorean theorem (a^2 + b^2 = c^2)

a = base

b = side

c = hypontenuse

then just plug the numbers into the formula > 6.3^2 + b^2 = 15.4^2

then subtract 6.3^2 from both sides > b^2 = 15.4^2 - 6.3^2

solve > b^2 = 197.47

Square root both sides and you get b = 14.1 mi as your answer
