Question

in the given figure angle b is equal to 55 degree if D is the midpoint of BC and a b is equal to AC then find the measurement of angle b a d​

Answer 1

Angle BAC=70

Because Triangle ABC is Isoceles therefore angle C is also 55

sum of all angles of a triangle is 180

55+55+BAC=180

110+BAC=180

BAC=70
