Question

find angle AOC and angle COF​

Answer 1

Answer:

AOC=BOD (LINEAR PAIR)

FOB=AOE (------"----- ---"----)

COF+AOC+FOB=180 (ANGLES ON SAME LINE)

Step-by-step explanation:

SO,

COF +40+135=180

COF=5

Answer 2

Answer:

angleEOD=angleCOF(vertically opp. angle)

angleAOC=angleBOD=135(vertically opp. angles)

angleAOE+angleEOD+angleBOD=180(linear pair)

40+angleEOD+135=180

EOD=180-(40+135)

=180-175

=5

angleCOF=5=angleEOD
