If a pool is 4 m wide and 16 m diagonally across, how long is the pool? (Pyth. Theorem)
alukav5142 [94]

Answer:

L=4\sqrt{15}\ m

or

L=15.49\ m

Step-by-step explanation:

we know that

Applying the Pythagorean Theorem in the rectangular pool

d^2=L^2+W^2

where

d is the diagonal of the pool

L is the length of the pool

W is the wide of the pool

we have

d=16\ m\\W=4\ m

substitute the given values

16^2=L^2+4^2

solve for L

L^2=16^2-4^2\\L^2=240\\L=\sqrt{240}\ m

simplify

L=4\sqrt{15}\ m

or

L=15.49\ m

I need help with this problem ASAP!
Karo-lina-s [1.5K]

Form a right angle triangle joining both given points to the origin, we get:

Perpendicular = 2 ( distance is always positive)

Base = 4 ( same logic)

Applying Pythagorus theorem

Hypotenuse = root of ( perpendicular squared + base squared)

Hypotenuse = root of 20 = 2 * root 5

Using x instead of theta

Sin x = perpendicular/hypotenuse

Cos x = base/hypotenuse

Sin x = -1/ root 5

Cos x = -2/ root 5

High probability of this answer being wrong.

Double check recommended.
