Apparently, we use "Permutation" when order doesn't matter. In that way, only possible outcomes can be calculated.
P (n, r) = n! ( (n - r)!
Unlike, We use "Combination" when order does matter. Combination gives us all possible values.
C (n, r) = n! / (n - r)! r!
Hope this helps!
The answer should be AC+BC
We can answer this by applying the rule called "Greater angle, greater side". This is where in any triangle, the opposite side of the larger angle is also longer.
So in this question, first we have to find the largest 2 angles, which is ∠ABC and ∠BAC with measures of 120° and 35° respectively. Therefore, from the diagram, the opposite sides of the angles are AC and BC.
Therefore, the answer should be AC+BC.
Short method: multiply constants
Long mothod: expand it
