Answer 2

Answer:

triangle is having 8 letters so we can say that there are 8!

as it has been mentioned that in the word triangle e and t have occupied and places there for out of 82 places have been occupied so we are left with 6 places and if in a question if there is no mention that if the repetition is allowed or not then then we will consider as repetition is allowed.
