Concept explainers
To classify: The pair of angles shown. The value of x in given figure.
Answer to Problem 3CYU
Both the given angles are supplementary angles because on joining they have a common ray and opposite rays form a straight angle of 180 degree. Accordingly the value of x is
Explanation of Solution
Given information:
The following figure:
Concept used:
If two adjacent angles have one common ray and opposite rays form a straight angle of 180 degree, then sum of these two angles is 180 degree.
Calculation: Based on above concept,
Conclusion: Thus, both given angles are supplementary angles so that the value of x is 75 degree.
