If a pool is 4 m wide and 16 m diagonally across, how long is the pool? (Pyth. Theorem)

or

Step-by-step explanation:

we know that

Applying the Pythagorean Theorem in the rectangular pool

where

d is the diagonal of the pool

L is the length of the pool

W is the wide of the pool

we have

substitute the given values

solve for L

simplify

i need the table so i can see

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
