Answer:

C. 1365

Step-by-step explanation:

The expression nCr can be written with the simple equation:

n! / ((n-r)! * r!)

So to evaluate 15C4:

15! / ((15-4)! * 4!)

= 1365

So 15C4 = 1365

Cheers.

Answer:

θ = 67.4°

Step-by-step explanation:

using the <u>SOHCAHTOA </u>method,

Here opposite is 12 cm, hypotenuse is 13 cm, adjacent is 5 cm.

Using the formula:

$sin(\beta ) = \frac{oppsoite }{hypotenuse}$

$sin(\beta ) = \frac{12}{13}$

$\beta = sin^{-1}(\frac{12}{13} )$

β = 67.4°
