Question

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

Answer 1

Answer:

The answer is the third one: x + y + z = 180 degrees

Step-by-step explanation:

in the picture we can tell angle x measures 90 degrees meaning that the third angle of the triangle also measures 90 degrees because the sum of the angles of a triangle is always 180 we can be sure that x + y + z = 180 degrees

Answer 2

Answer:

y + z = x

Step-by-step explanation:

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

x is an exterior angle of the triangle, thus

y + z = x
