1. joshua is trying to find the measure of the angle indicated in bold (-5+12x). his work is shown below and it
contains a mistake. explain the mistake and then show the correct solution.
note: when explaining the mistake, make sure to indicate how the solution is wrong and how it needs to be
corrected.
joshua's solution
-5 + 12x + 10x + 9 = 180
22x + 4 = 180
22x = 176
x=8

-5 + 12(8) = -5 + 96 = 919

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 .
