To find:the value of x
Answer to Problem 11CE
The value of x is
Explanation of Solution
Given information:The diagram below
Concept Involved:
Exterior angle Theorem states that the exterior angle of a
The measure of linear pair adds up to give 180 degrees.
Calculation: One of the opposite angle to exterior angle is given, other opposite angle to exterior angle can be found by using the fact that linear pair add up to 180 degrees, so other opposite angle is given by:
Use the exterior angle theorem to set up an equation for the given triangle
Simplify the equation
Conclusion:
The value of x is
