Triangle xyz slides 2 units left and 1 unit down on the coordinate plane. if the original measure of angle x was 40 degrees, what is the measure of angle x'? 30 degrees 40 degrees 60 degrees 140 degrees

What is the missing step in this proof ?

Which of the expressions (on the photo document i inserted) together represent all solutions to the following equation? 8cos(12x)+4=-4 *the answer should be in degrees.* > i would like for someone to explain the process to find the solutions for this.

A(1,1) b(-3,0) c(-4,-1) d(3,-2) drag it to correct position
