If isosceles triangle ABC has a 130° angle at vertex B, which statement must be true? O mzA= 15° and m2C = 35°
mZA+mZB = 155
OmZA+ m2C = 60°
OmZA= 20° and mzC = 30°

Triangle xyz, with vertices x(-2, 0), y(-2, -1), and z(-5, -2), undergoes a transformation to form triangle x′y′z′, with vertices x′(4, -2), y′(4, -3), and z′(1, -4). the type of transformation that triangle xyz undergoes is a . triangle x′y′z′ then undergoes a transformation to form triangle x′y′z′, with vertices x″(4, 2), y″(4, 3), and z″(1, 4). the type of transformation that triangle x′y′z′ undergoes is a .

Benjamin believes that ¼ % is equivalent to 25%. is he correct? why or why not?

The ideal mechanical advantage of a machine reflects the increase or decrease in force there world be without friction, it is always greater than the actual mechanical advantage because all machines must overcome friction. true false
