Answer:
105 , 60 is the correct answer
Answer:
if angle A= angle C
therefore , angle CAD = angle ACD
therefore , 60°= 60°
Now,In triangle ACD,
angle A+angle D+angle C=180°
60°+angle D+ 60°=180°
angle D +120° =180°
angle D=180°-120°
therefore, angle D = 60°
therefore ,angle CDA = 60°
if angle CDA = 60°
therefore, angle BDA = 1/2 CDA
angle BDA = 1/2×60
angle BDA =30°
Then, In triangle BCD
angle CBD +angle BDC + angle BCD=180°
45°+ 30°+ angle BCD =180°
75°+ angle BCD= 180°
angle BCD = 180°-75°
angle BCD =105° ans
