Answer 1

Răspuns:

30: a. 30, 150, 60, 165

Explicație pas cu pas:

a.

<BOC +< AOB= 180

<BOC=5<AOB=> 6<AOB=180=> <AOB=30=> <BOC=150

<BOC=<BOP-<COP

<BOP=90=> <COP=150-90=60

ON-bisectoarea <BOC=> <BON=<NOC=150/2=75

<AON&<COR-opuse la vârf => <COR=<AON=<AOB+<BON=30+75=105

<POR=<COR+<POC=105+60=165

b.

OM-bisectoarea <AOB=> <MOB=<AOM=30/2=15

<MON=<MOB+<BON=15+75=90

c.

Fie ON-bisectoarea <BON => <BOT=<TON=75/2=37,5

<MOT=<BOT+<MOB=37,5+15=52,5=> <MOT=<MOP/2=>OT-bisectoarea <MOP

=> bisectoarea <MOP=bisectoarea <BON
