Answer:
19448 ways
70572902400 ways
Step-by-step explanation:
(a)
To arrange 17 books on a shelf from a possible we use the combination formula :
nCr = n! ÷ (n-r)!r!
17C10 = 17! ÷ 7! 10!
17C10 = 19448 ways
To arrange the books in alphabetical order :
2)
In question, 2, the order of arrangement matters ; hence, we use permutation ;
nPr = n! ÷ (n-r)!
17P10 = 17! ÷ (17 - 10)! = 17! ÷ 7!
17P10 = 70572902400
When you draw a diagonal line from Y to W, you will create two congruent triangles.
Each of these triangles will have three sides of different lengths, making them scalene triangles.
In each of these triangles, there will be one 90° angle, right angle, and two acute angles (less than 90°). This would classify these triangles as right triangles based on the angles.
Both triangles are right, scalene triangles.
