Given: ∠A and ∠B are supplementary angles. m∠A=4x−16; m∠B=2x+4

Prove: m∠B=68°

Drag and drop reasons into the boxes to correctly complete the proof.

Statement Reason
∠A and ∠B are supplementary angles. Given
m∠A=4x−16; m∠B=2x+4 Given
m∠A+m∠B=180° Definition of supplementary angles
4x−16+2x+4=180 Response area
6x−16+4=180 Simplify.
6x−12=180 Simplify.
6x=192 Response area
x=32 Response area
m∠B=2(32)+4 Substitution Property of Equality
m∠B=64+4 Simplify.
m∠B=68° Simplify.

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.

your answer is -9
