The answer for the completion exercise shown in the image attached above is:
1) Multilplication property of equality (If you multiply mEFG+mGDE=360° both sides of the equation by 1/2, you obtain 1/2(mEFG)+1/2(mGDE)=180°).
2) m∠D=1/2(mEFG)
3) m∠F=1/2(mGDE)
4) By the substitution property of equality (Because if you substitute m∠D=1/2(mEFG) and m∠F=1/2(mGDE) into 1/2(mEFG)+1/2(mGDE)=180°, you obtain: m∠D+m∠F=280°).
The first part is $15.00
Second part is $13.50

Answer:
m = 
Step-by-step explanation:
Given
3m + 8 = 15 ( subtract 8 from both sides )
3m = 7 ( divide both sides by 3 )
m =
