Question

Part 1: [4 points] Find the measure of angle CFD.

Part 2: [6 points] Explain how you found the measure including the angle relationships. (complementary, supplementary, vertical, etc.)

Answer 1

EFD=AFB=43 ---> opposite angles are equal
EFD+CFD+CFB=180 ------>supplementary angles sum up to 180
43+CFD+90=180----->CFD=90 is given
CFD=180-90-43=47

Answer 2

typo:in 2nd last line,the reason is CFB is given
