Answer: The correct option is (D) 24.

Step-by-step explanation: We are given to find the value of x from the given figure, where MO is an angle bisector.

From the figure, we note that

MO is the angle bisector of angle M in ΔLMN, where

ML = x cm, MN = 12 cm, LO = 41 cm and ON = 7 cm.

We have the following theorem :

<u><em>Angle bisector theorem </em></u>: An angle bisector of a triangle will divide the opposite side into two segments that are proportional to the other two sides of the triangle.

Applying the above theorem in the given triangle LMN, we have

$\dfrac{ML}{LO}=\dfrac{MN}{ON}\\\\\\\Rightarrow \dfrac{x}{14}=\dfrac{12}{7}\\\\\Rightarrow x=\dfrac{12\times 14}{7}\\\\\Rightarrow x=24.$

Thus, the required value of x is 24.

Option (D) is CORRECT.

Prove that the natural number x is prime if and only if x>1 and there is no positive integer greater than 1 and less than or

There are several ways to prove a mathematical statement. These ways include: by contradiction, by induction, contraposition, etc

<h3>How to prove the statement by contradiction</h3>

To prove the statement, we make use of proof by contradiction

From the question:

x is a composite number such that: x > 1

This means that 1 < a < x is a factor of x

This can be represented as:

$x = a * b$

Where:

a and b are positive integers
1 < a, b < x

Assume that b is less than or equal to a.

Also, let

$b > \sqrt x$

This means that:

$\sqrt x < b \ge a$

The above becomes

$\sqrt x < a$

Rewrite as:

$a > \sqrt x$

So, we have:

$x = a * b > \sqrt x * \sqrt x = x$

The above means that:

$x > x$

The above inequality is a contradiction because, a number x cannot be greater than itself

This means that, the supposition is wrong.

Hence, the given statement has been proved by contradiction
