write a paragraph, flowchart, or 2-column proof for the following:
given: m< 1 = 27 degrees, < 1 and < 2 are supplementary
prove: m< 2 = 153 degrees

see the procedure

Step-by-step explanation:

we know that

m∠1+m∠2=180° > supplementary angles (form a linear pair)

we have

m∠1=27° > given problem

substitute the measure of m∠1 in the equation above and solve for m∠2

27°+m∠2=180°

Subtract 27° both sides

27°+m∠2-27°=180°-27° > by subtraction property of equality

m∠2=153°
