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

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 class=

Respuesta :

Answer:

B

Step-by-step explanation:

We can see that angles r and x are both on a line cut by a perpendicular line. This means that the angles on the line should add up to 180.

[tex]x+r=180[/tex]

We can move x to the other side.

[tex]180-x=r[/tex]
