Math Problem Statement

Find the value of x based on the given intersecting lines and angle measures.

Solution

The image shows a diagram with several intersecting lines, creating multiple angles. Based on the given information, we are tasked with finding the value of xx.

Step 1: Identify the angles

  • The angle labeled 118118^\circ is highlighted in green.
  • The angle labeled 106106^\circ is highlighted in orange.
  • The angle labeled xx is highlighted in blue.

Step 2: Analyze the relationships between angles

  • Since the lines are intersecting, we can use angle relationships such as vertical angles (which are equal) and linear pairs (which add up to 180180^\circ).

From the diagram:

  1. The 118118^\circ angle and the angle adjacent to it on the same straight line should form a linear pair, summing to 180180^\circ. Therefore, the angle adjacent to 118118^\circ is 180118=62180^\circ - 118^\circ = 62^\circ.

  2. The 106106^\circ angle forms a linear pair with the angle next to it, which means the adjacent angle is 180106=74180^\circ - 106^\circ = 74^\circ.

  3. Since xx is vertically opposite the angle that forms a linear pair with 106106^\circ, it should be equal to 7474^\circ.

Therefore, the value of xx is 7474^\circ.

If you have any questions or would like a more detailed explanation, feel free to ask! Here are some related questions for further practice:

  1. What is the measure of the angle opposite to 118118^\circ?
  2. How do you find the measure of an angle that forms a linear pair with a given angle?
  3. What is the relationship between vertically opposite angles?
  4. How can you confirm the correctness of angle measures in a geometric diagram?
  5. What other angle relationships can be identified in a complex intersecting line diagram?

Tip: Remember that in intersecting lines, vertically opposite angles are always equal, which can simplify finding unknown angles!
