Question

Plz solve this fast...... Thank yoe

Answer 1

Step-by-step explanation:

in the triangle ODC

OD =OC (radius)

so DOC is isosceles triangle

so angle CDO =30

so angle DOC =180-30-30=120

angle DOC =120

so linear pair of DOC is angle BOD

which is 60

and triangle BOD is also a isosceles triangle with OB =OD (radius)

so remaining angles are equal so

2x=120

x=120/2=60

so angle BDO =60

Answer 2

Answer:

COD=(180-130)°=50°(LINEAR PAIR)

CDO=(50+30)°+CDO=180°(ANGLE SUM PROPERTY OF TRIANGLE)

CDO=(180-80)°=100°(LINEAR PAIR)

BDO=CDO=100°(ALTERNATE INTERIOR ANGLE)
