<u>Trigonometric Ratios</u>

The ratios of the sides of a right triangle are called trigonometric ratios.

Selecting any of the acute angles, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides and the hypotenuse.

The given right triangle has an angle of measure 51° and its adjacent leg has a measure of 19 units. It's required to calculate the hypotenuse of the triangle.

We use the cosine ratio to calculate x:

\displaystyle \cos\theta=\frac{\text{adjacent leg}}{\text{hypotenuse}}

\displaystyle \cos 51^\circ=\frac{19}{x}

Solving for x:

\displaystyle x=\frac{19}{\cos 51^\circ}

\displaystyle x=\frac{19}{0.6293}

x = 30.2 units

The number of permutations of the 25 letters taken 2 at a time (with repetitions) is:25^{2}
The number of permutations of the 9 digits taken 4 at a time (with repetitions) is:
9^{4}
Each permutation of letters can be taken with each permutation of digits, therefore the total number of possible passwords is:
25^{2}\times 9^{4}=4,100,625
