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. fill in the blanks.

statement: reason:
4x-16+2x+4=180

6x=192

x=32

options:
(substitution property of equality, reflective property of equality, addition property of equality, division property of equality, symmetric property of equality, transitive property of equality, angle addition postulate)
