Step-by-step explanation:

Given that,

Perpendicular = 17 units

Hypotenuse = 25 units

We need to find the value of x.

Using Pythagoras theorem to find x.

Hypotenuse² = base²+perpendicular²

25² = x² + 17²

x = 18.3 units

So, the value of x is equal to 18.3 units. No, the sides do not form a Pythagorean triplet.

Anastaziya [24]
You need to know in how many ways you can choose 10 out of 25 items when order does not matter. This is a combination problem.

_{n}C_{r} =  \dfrac{n!}{(n - r)!r!}

_{25}C_{10} =  \dfrac{25!}{(25 - 10)!10!}

_{25}C_{10} =  \dfrac{25 \times 24 \times 23 \times 22 \times 21 \times 20 \times 19 \times 18 \times 17 \times 16 \times 15!}{15! \times 10 \times 9 \times 8 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1}

_{25}C_{10} =  \dfrac{25 \times 24 \times 23 \times 22 \times 21 &#10;\times 20 \times 19 \times 18 \times 17 \times 16}{10 \times 9 \times 8 \times 7 \times 6 \times 5 \times 4 \times 3 &#10;\times 2 \times 1}

_{25}C_{10} =  \dfrac{23 \times 11 \times 20 \times 19 \times 2 \times 17}{1}

_{25}C_{10} = 23 \times 11 \times 20 \times 19 \times 2 \times 17

_{25}C_{10} = 3,268,760
