Answer: First let’s find x.
A straight line adds up to 180 degrees. So wen know that X and the 81 degree angle should add up to 180, so x+81=180 is our equation. Let’s solve.
Subtract 81 from 180
You get x=99 degrees.
Let’s now find Y.
We know because of the alternate interior angles property that x will have to equal 3y-9. We already know x is 99. Let’s set up an equation. 3y-9=99 let’s add our 9. We get 108. Divide by 3. We get y=36.

Answer:
In case of true false questions there are two ways to answer each questions and we have 10 questions . So as per the rule of permutation we have (2×2×2×2×2×2×2×2×2×2) or 2^10 or 1024 no. Of ways to answer 10 true false questions in the exam.

The handshake is an illustration of combination, and the values of n and r are 21 and 2, respectively
<h3>How to determine the values of n and r?</h3>
The number of students in the class is 21.
This represents the value of n
i.e. n = 21
Each student shakes hand with another student (i.e. 2 students per handshake)
This represents the value of r
i.e. r = 2
Hence, the values of n and r are 21 and 2, respectively
