Question

in the adjoining figure , find the measure of angle BDC and angle ACD​

Answer 1

Answer:

angle BDC = 40, angle ACD = 133

Step-by-step explanation:

Since, AB = AC & DB =DC

angle(ABC) = angle(ACB) = x

angle(DBC) = angle(DCB) = 70

In triangle ABC

x + x + 54 =180

2x = 126

x= 63

In triangle BDC

angle(BDC) + 70 + 70 =180

angle(BDC) =40
