Will give brainliest  given: quadrilateral defg is inscribed in circle p. prove: m∠d+m∠f=180∘ drag and drop an answer to each box to correctly complete the proof.

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°).

Where are the answer choices?
