Step-by-step explanation:
How many books are there?
6+5+4+3 = 18 books total
How many are adventure books?
3
3 out of 18 books are adventure books
Robero has a 3/18 probability of choosing an adventure book.
Your teacher might want that probability in the lowest possible form. That is because it is the easiest to use and to understand.
You can do this by dividing both numbers by the "numerator" which is the first number in the fraction, (the adventure book count).
3/3 = 1
18/3 = 6
So the fraction can be reduced to 1/6.
Robero has a 1/6 chance of choosing an adventure book.

Answer:
That is an obtuse scalene triangle
Step-by-step explanation:
Scalene- has no congruent sides
Obtuse - has an angle that is greater than 90
we can use Pythagorean theorem to confirm this
The Pythagorean theorem states that in an obtuse triangle the hypotenuse squared is greater than the two legs squared added together
so basically 
therefore it is an obtuse scalene
