Question

please do this sum it's vry imp
question 7 plzzz

Answer 1

hey friend!

solution here!

triangle AOD & triangle BOC are vertically opposite angle

so

AOD = BOC = 64°

now

AC is supplementary angle
so

AOD+ COD = 180°

64° +COD= 180°

COD= 180°-64°

COD = 116

Now
angle OBC = angle ODA= 36° ( alternative angle)

so IN triangle OAD

64°+36° +OAD = 180°

OAD = 180°- 100

OAD = 80° Ans

[2)

in triangle OCD

COD+ ODC +OCD = 180°

116° +28° + OCD = 180°

OCD = 180° - 144

OCD= 36= Ans!!

hope it's helpful ✌✌
