Таблица 7.4 Смежные и вертикальные углы(фото есть)  Помогите прошу!!!

1. <AOB = 180° - <BOC = 180° - 23° = 157° ;
<AOD = <BOC = 23° ;
<COD = 180° - <BOC = 180° - 23° = 153°

2. <BOC = 180° - ( <BOF + <COE )
<BOF = <EOD = 32°
<COE = 32° (по рис.)
<BOC = 180° - ( 32° + 32° ) = 180° - 64° = 116°

3. <FOE = 180° - <FOB
<FOB = <FOA + <AOB
<FOA = <COD = 25°
<FOE = 180° - ( 25° + 55° ) = 80°

4.
<DOB = 360° - 210° = 150°
<AOD = 180° - 150° = 30°

5.<AOF = 180° - ( <FOE + <AOB )
<FOE = <BOC = β
<AOB = α
< AOF = 180° - ( α + β )

6. <EOD = 180° - ( <DOS + <BOS )
<DOS = <FOA = β
<BOS = α
<EOD = 180 - ( α + β )

7. <2 и <3 смежные => <2=<3 ; <1 = <2 => <1=<3
<3 и <4 односторонние => <3 + <4 = 180°

8. <BAC = <1 (т.к. они вертикальные)
<ACD = 180° - <2 (т.к. они смежные)
<1 = <2 = α
<BAC + <ACD = <1 + ( 180° - <2 ) = α + 180° -α => <BAC + <ACD = 180°
