In the diagram below, DE is parallel to XY. What is the value of x?

the value of x is

115°+y=180 (being linear pair)

y =180°-115°

therefore, the value of y is 65°.

now again x=y=65°(being corresponding angle)

so, the value of x is 65°.

hope u understood..

1/5x+9 2/5y+7

step-by-step explanation:

(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
