Answer:
The correct option is C) x + y + z = 180 degrees
Step-by-step explanation:
Consider the provided information.
It is given that four r, x , y and z.
If x , y and z are the interior angle then,
According to the Angle sum property of triangle: The sum of three interior angles of triangle is 180°.
Therefore, the sum of x , y and z must be equal to 180 degrees.
Hence, the correct option is C) x + y + z = 180 degrees
