Question

What’s the length of a leg of an isosceles right triangle whose hypotenuse is 100?

Answer 1

Answer:

The length of a leg of the isosceles triangle is 50√(2

Step-by-step explanation:

Since it is an isosceles right triangle, the length of the adjacent and the opposite is the same value which is let’s say x.

Mathematically; the square of the hypotenuse equals the square of the adjacent plus the square of the opposite according to Pythagoras.

Thus;

100^2 = x^2 + x^2

10000 = 2x^2

divide the through by 2, we have;

x^2 = 10,000/2

x^2 = 5,000

x = √5,000

x = √2,500 * 2

x = 50√2
