Question

in quad ABCD ANGLE A=70 ANGLE B=130 BISECTORS OF ANGLE C AND D MEET AT O FIND ANGLE COD

Answer 1

Step-by-step explanation:

In above quadilateral abcd angle A=70and b=130 and angle 1=2and angle 3 =4

70+130+c+d=360(exterior angles sum =360)

c+d=160

1+2+3+4=160 ( c=1+2. and d =3+4)

angle 1=2 and angle 3=4 so it become 2(2+3)

2(2+3)=160

2+3=80

In triangle cdo

c+d+o=180

80+o=180

o=100

so angle cod = 80

Answer 2

angle COD will be 100°
