A new pipeline is being created to shorten the distance it has to travel to get from point A to point B. The original pipeline r
an at a 90 angle from point A to point B and was 20 miles on one side and 15 miles on the other. The new pipeline go straight from A to B. How much shorter will the new pipeline be?
<span>so use pythagorean theorem where a^2+b^2=c^2 a and b are legs c=hypotonuse in a right triangle
90 degrees=right riangle so we have 20 and 15 these are the legs subsitute 20^2+15^2=c^2 400+225=c^2 add 625=c^2 square root both sides 25=c new pipe=25 how much shorter old=20+15=35 how much shorter is 25 than 35 35-25=10 answer is 10 miles</span>
