Find the value of x and y please

The answer to your question is  x =  and y =

Step-by-step explanation:

To find x and y use trigonometric functions

- Find x

To find x use the trigonometric function cosine

       cosine Ф = adjacent side/hypotenuse

- Solve for adjacent side (x)

       x = hypotenuse x cos Ф      

- Substitution

      x = 14 cos 60

Simplification

      x = 14 (0.5)

      x = 7

- Find y

-Find the length of the opposite side of the small triangle

 Opposite side = sine Ф x hypotenuse

 Opposite side = 14 x sin 60

Opposte side = 14 (/2)

Opposite side = 7

- Find the length of y

 y = Opposite side/sin Ф    

 y = /

 y = 14

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
