Question

Help on Triangle Angles....

Answer 1

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

A triangle is shown with a leg extending past the top vertex. The vertices are labeled ABC. Angle y is located inside the trian (4 points)

x + z = y
180 degrees – x = r
x + y + z = 180 degrees
x + y + z = 90 degrees

Answer 2

here's the picture

Answer 3
