Question

angle abc is equal to 70 degree angle BC is equal to 60 degree then CD b is equal to​

Answer 1

Answer:

See triangle ABC

Apply angle sum property

70+60+angle BAC =180

So angle BAC is 50 degree

Now you can put the theorem angle on the same segment are equal

So angle CBD is also 50 degree

Answer 2

Answer:

ABC = 70° BCA = 60 ° as we know that in a triangle the sum of angles is 180° SO let CDB be x 70 + 60 + CDB = 180 130 + CDB = 180 CDB = 180 - 130 = 50
