How can I find the legs of a right triangle using only the hypotenuse length, 600, and the fact that all the sides have to add up to 1400?

Let x and y be the sides.

By Pythagorean Theorem, x^2 + y^2 = 600^2.
x+y+600 = 1400

a + b + c = 1400

a + b + 600 = 1400
a + b = 800

using Pythagorean theorem
a^2 + b^2 = 600^2

a + b = 800
a^2 + b^2 = 600^2

solve simultaneously
I got
a = 258.579
b = 541.421

or
a = 541.421
b = 258.579

To find the lengths of the legs of a right triangle given the hypotenuse length and the sum of all the sides, you can use the Pythagorean theorem and some algebraic equations.

Let's say the lengths of the legs are represented by variables a and b, and the hypotenuse length is given as c. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides:

a^2 + b^2 = c^2

In this case, you are given that the hypotenuse length is 600 and the sum of all the sides is 1400. So, you can set up the following two equations:

a + b + c = 1400 -- (equation 1)
a^2 + b^2 = c^2 -- (equation 2)

Substituting the given values, equation 1 becomes:

a + b + 600 = 1400

We can now isolate one variable, say a, in equation 1 by rearranging the equation:

a = 1400 - b - 600

Now, substitute this value of a in equation 2:

(1400 - b - 600)^2 + b^2 = 600^2

Simplifying further, you can expand and solve this equation for b:

(800 - b)^2 + b^2 = 360000

Taking the square root of both sides, you can solve for b:

800 - b + b = √(360000)

800 = √(360000)

Squaring both sides to eliminate the square root:

800^2 = 360000

640000 = 360000

So, the equation is not valid, which means there are no real solutions for the lengths of the legs of the right triangle that satisfy the given conditions.

Hence, it is not possible to find the lengths of the legs of the right triangle using only the hypotenuse length (600) and the fact that all the sides have to add up to 1400.
