The first three are dependent variables as the outcomes could potentially change due to any of these circumstances. The last one is an independent variable due to the fact that rolling a die several times will not affect the next outcome.
A=x B= 2x C=3x If you add them up = 6x =180 ÷6 both sides x=30 A=30 B=60 C=90 one angle is 90 degrees so the triangle is classified as a right triangle
