Step-by-step explanation:
The correct answer is: AB = 3.11
Explanation:
Since
--- (1)
= 50°
base = 2
And hypotenuse = AB
Plug in the values in (1):
(1) => cos(50°) = 2/AB
=> AB = 2/0.643
=> AB = 3.11

Method One
Your calculator might be able to do this. Mine does it like this.

=
15
Method 2
You could simply set up 6C2
This gives you
Method Three
You only have to do this a couple of times to see how the cancellation works.
After all the cancellation takes place you have
6*5/2 = 15
