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  

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

b
