Respuesta :
The length of the third side of the right triangular flower bed is 10 feet.
A right-angled triangle is a triangle with one of its interior angles equal to 90°. The side opposite to the right angle is the largest side and is referred to as the hypotenuse. Hypotenuse is always greater than any of the other two sides.
If two of the sides of the flower bed are 7 feet long each, then these are the sides adjacent to the right angle. We are to find the length of the third side, which is the hypotenuse, using the Pythagorean theorem.
Pythagorean Theorem states that the square of the length of the hypotenuse of a right-angled triangle is equal to the sum of the squares of the two other sides.
c^2 = a^2 + b^2
where a and b are the adjacent sides to the right angle
c is the hypotenuse
c^2 = 7^2 + 7^2
c^2 = 49 + 49
c^2 = 94
c = 9.899
Hence, he length of the third side of the right-angled triangular flower bed is 10 feet.
