Hello!
.
The answer to your question is 495 ways.
.
n = 12
r = 4
.
nCr = n1 / (n-r)! r1
12C4 = 12! / (12-4)! 4!
12C4 = 12x11x10x9x8! / 8! 4!
12C4 = 11880 / 24
12C4 = 495

Answer:
Step-by-step explanation:
Since cotangent of angle is:
And
- cos λ = x/1, sin λ = y / 1
The value of cot λ is:
- cot λ = x/y = - 0.358/0.934 = - 0.383 (rounded)
