初一数学题（余角和补角）如图（不要给我写些“两对角相等”的东西）

∵∠ AOC = 28°24′
∴ ∠ AOD = 180° - 28° 24′
= 151° 36′
∵∠ AOD = ∠ AOE + ∠ EOD
∠AOD = 2∠ EOF+ ∠ EOD = 151° 36′ ①
∵ ∠ AOE + ∠ EOB = 180 °
2∠EOF + ∠ EOD + ∠ DOB = 180° ②
①代入 ②
∠ DOB= 180° - 151° 36′ = 28° 24′
∴ ∠ EOD = 28° 24′
∴ 2∠ EOF = 151° 36′- 28° 24′= 123° 12′
∴ ∠ EOF= 61.5° 6′ = 61° 36′
