Question

pleaseeeeeeeeee solve question with proof

Answer 1

PQ || RS
therefore angle AEF + BFC = 180 ( co int angls) .....1


triangle AOE is congurent to triangle OEC
therefore angle AEO = OEC
similarly angle BFO = OFC

1/2 AEF + 1/2BFC = 90
OEC + OFC = 90
EOF + OEC + OFC = 180 (angle sum property)
EOF + 90 = 180
EOF = 90

hope this would help u:)
