Answer:
nCr.
Step-by-step explanation:
That would be nCr,
For example
5C2 = 5! / 2! (5-2)!
= 5! / 2!3!
Mathematical proofs are used to prove or disprove mathematical statements.
<h3>Mathematical theorems </h3>
The theorems to use are:
- The sum of angles on a straight line is 180 degrees
- Alternate angles are congruent
<h3>The proof</h3>
From the question, we have:
This means that, ABC is a triangle
Also, we have:
BP || AC
This means that lines BP and AC are parallel
So, the following angles are congruent by alternate angle theorem
.
The angles on a straight line add up to 180 degrees.
So, we have:

By substitution, the above equation becomes

Rewrite the equation as:

Hence, the statement that
has been proved
