Given:
Consider the below figure attached with this question.
Angles of a triangle are x, y and z.
To find:
The values of x, y and z.
Solution:
If two angles are linear pair, then their sum is 180 degrees.



Similarly,



According the the angle sum property, the sum of all angles of a triangle is 180 degrees.





Divide both sides by -5.

The value of x is 36.



Now,



Therefore, the values of x, y and z are 36, 67 and 77 respectively.
Answer:
