Question

Which relationship is always true for the angles r, x, y, and z of triangle ABC?

x + z = y

180 degrees − x = r

x + y + z = 180 degrees

x + y + z = 90 degrees

Answer 1

The correct option is C) x + y + z = 180 degrees

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
