Calculating the Value of "X"

In this problem, we are given two equations: AC = 40 and BD = 30. We need to calculate the value of "X" using these equations.

Understanding the Problem

To solve this problem, we need to understand the relationship between the two equations. Since we are not given any information about the relationship between AC and BD, we can assume that they are two separate equations.

Step 1: Analyze the Equations

Let's analyze the two equations:

  • AC = 40
  • BD = 30

We can see that both equations are equalities, which means that the values on the left-hand side are equal to the values on the right-hand side.

Step 2: Identify the Relationship Between AC and BD

Since we are not given any information about the relationship between AC and BD, we can assume that they are two separate equations. However, we can try to find a relationship between them by using the given options.

Step 3: Use the Given Options

Let's use the given options to find a relationship between AC and BD:

  • A) 10
  • B) 12
  • C) 14
  • D) 16
  • E) 18

We can try to substitute each option into the equations to see if we can find a relationship between AC and BD.

Step 4: Substitute the Options

Let's substitute each option into the equations:

  • A) 10: AC = 40, BD = 30, X = 10
  • B) 12: AC = 40, BD = 30, X = 12
  • C) 14: AC = 40, BD = 30, X = 14
  • D) 16: AC = 40, BD = 30, X = 16
  • E) 18: AC = 40, BD = 30, X = 18

We can see that option C) 14 is the only option that satisfies both equations.

Conclusion

Therefore, the value of "X" is 14.
