Area of a triangle = $\frac{1}{2}$ · base x height
   180 = $\frac{1}{2}$ · base x 40
   180 = 20 · base
      9 = base

Pythagorean Theorem:
base² + height² = hypotenuse²
9²    + 40² = hypotenuse²
81 + 1600 = hypotenuse²
1681    = hypotenuse²
   √1681           = √hypotenuse²
   41    = hypotenuse

Answer: the length of the hypotenuse is 41 m

How many words of five letters can be created that start with the letter T, contain 2 other consonats and end with 2 vowels? Not

Jet001 [13]

If we're only counting 5 vowels (A, E, I, O, U) and 20 consonants (everything else, minus T), then there are

$\dbinom52=\dfrac{5!}{2!(5-2)!}=10$

ways of picking the vowels, and

$\dbinom{20}2=\dfrac{20!}{2!(20-2)!}=190$

ways of picking the consonants.

We want the word to start with T, and we'll allow any arrangement of the other 4 letters, so that the total number of words is

$4!\dbinom52\dbinom{20}2=\boxed{45,600}$

Keep in mind that this means words like TRIES and TIRES are treated as different.
