A quadtriatel is said to contain perpendicular diagnols if four go 90 degree angles are formed at the intersection of these lines
Because we're treating the swimming pool as a standard rectangle, rather than a three dimensional shape, we can use the formula L * W = A to calculate the length of the pool.
Length * Width = Area
We've established two key bits of information, and with them we can solve for the final piece.
Length * 4 = 16
4l = 16
Divide both sides by 4.
l = 4
<h3>The length of the pool is 4 meters.</h3>
25% because if you simplify the fraction, it would be 1/4 and that is equal to 0.25
ΔABC is a 45 - 45 - 90 triangle. The pattern of its sides is as follows:
Each leg = 1 unit (and both legs are that way, since the triangle is isosceles - so two sides are the same)
Hypotenuse = √2 units.
So if we know either leg, we multiply by √2 to get the hypotenuse. In reverse, we divide by √2 if we know the hypotenuse to get the measurement of a leg.
Our problem tells us that the hypotenuse AC is 10 units. We divide 10 by √2 to get the measurement of leg AB. Since it's a 45 -45 - 90 triangle, AB = BC.

to rationalize the radical

Thus, each leg is 5\sqrt{2} [/tex].
Answer:
129 - 280 = 51.. So the answer is 51%
