Find the value of the combination. 10C0
Andrej [43]

Answer:The formula for a combination of choosing r unique ways from n possibilities is:

nCr  =   n!

  r!(n - r)!

where n is the number of items and r is the unique arrangements.

Plugging in our numbers of n = 10 and r = 0, we get

10C0  =   10!

  0!(10 - 0)!

10C0  =   3,628,800

  3,628,800

2 or more angles are supplementary if their sum is 180°. An angle is 4 times the value of its supplement.
mr_godi [17]

Answer:

Smaller Angle : 36 degrees

Bigger Angle : 144 degrees

Step-by-step explanation:

So we can name the smaller angle x and the larger one 4x. We can add them and make the answer 180. x+4x=180, 5x=180, x=36

Smaller angle : x=36

Bigger Angle : 4x=36*4=144

mote1985 [20]

Answer:

  • 1. Adjacent, 2. Vertical, 3. Neither

Step-by-step explanation:

1.

  • The first pair is adjacent as they have common side.

2.

  • The second pair is vertical as opposite angles of the crossed lines.

3.

  • The third pair has no relationship with each other, so neither is the answer.
