Answer: Symmetric Property
Step-by-step explanation:
The symmetric property of equality is given by :
The given statement : If l = m, then m = l.
We can see that the symmetric property of equality justifies the above statement.
The other properties fro any numbers a,b and c are :
Multiplication property : if a=b , then ac=bc
Subtraction property : if a=b, then a-c=b-c
Reflexive property : a=a

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.
