You would do 2 · 26 · 26 = 1,352 different arrangements

Well if W is fixed then the second letter could be any of the 25 left over. for each of those 25 there is 24 possible other letters. So for one it should be 25X24. For 2 it should be 2X25X24. I think..

The answer would be H. All you have to do for a problem like this in the future are to add the 3 different angles together and make sure they equal 180 degrees.

Usimov [2.4K]

Answer:

2x + 3x + 5x = 180

10x = 180

x = 18

2x = 36, 3x = 54, 5x = 90

They add up to 180 (definition of sum of angles of a triangle.)
