Answer:

if sin (x-3) degrees = cos (2x+6) degrees, find the value of x.

----------

Note: sin and cos are complementary functions....

sin(x) = cos (90-x)

-------------------

Your Problem:

sin(x-3) = cos(90-(x-3))

Equation:

90-[x-3] = 2x+6

90-x+3 = 2x+6

3x = 93-6

x = 31-2

x = 29

Combination will be used here as teams are a group.

So using combination:

No. of combination of 'n' things taken 'r' at a time

$\limits^n {C} \,_r$ = $\frac{n!}{r! (n-r)!}$

here n = 11 ,

r = 9

11C9 = $\frac{11!}{9! (11-9)!}$ = $\frac{11!}{9! (2!)}$

11C9 = 55
