Math Problem Statement
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 .
Step 1: Identify the angles
- The angle labeled is highlighted in green.
- The angle labeled is highlighted in orange.
- The angle labeled 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 ).
From the diagram:
-
The angle and the angle adjacent to it on the same straight line should form a linear pair, summing to . Therefore, the angle adjacent to is .
-
The angle forms a linear pair with the angle next to it, which means the adjacent angle is .
-
Since is vertically opposite the angle that forms a linear pair with , it should be equal to .
Therefore, the value of is .
