| March 3, 2021 | education
To solve this problem, we use the Pythagorean theorem, according to which in a right-angled triangle the square of the hypotenuse is equal to the sum of the squares of the legs.
Let’s say the hypotenuse is x. Then:
x ^ 2 = 4 ^ 2 + 5 ^ 2;
x ^ 2 = 16 + 25;
x ^ 2 = 41;
x = √41.
Answer: The hypotenuse is √41.
