In the applet above right triangle ABC with a 72 degrees. For triangles with an angle of 72 degrees the ratio of the side opposite 72 degree angle compared the hypotenuses 19/20. if the hypotenuse, has length of 100 what is the length of the side opposite 72 degree angle, AC?

1 / 362880

Step-by-step explanation:

There are 9 possible names that could be first.

After that, there are 8 possible names that could be second.

After that, there are 7 possible names that could be third.

So on and so forth.

So the number of permutations is:

9×8×7×6×... = 9! = 362880

The probability of randomly selecting the one order used in the spelling bee is therefore:

P = 1 / 362880
