Question

Write a paragraph, flowchart, or 2-column proof for the following:

Given: m∠1=〖27〗^0, ∠1 and ∠2 are supplementary

Prove: m∠2=153⁰

really in need of answers.

Answer 1

see the procedure

Explanation:

we know that

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

we have

m∠1=27°

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°
