Answer:
angle BAC = 56.5 degree
Step-by-step explanation:
In the given circle O, AO and BO are the radius of the circle
AO and BO are same
So the angle opposite of AO and BO are also same
Angle BAC = angle ABO
WE know the sum of angles in a triangle is 180 degree
Angle BAC + ABO + O = 180 degree
Angle O = 67 degree
angle ABO = angle BAC
BAC + BAC + 67 = 180
2BAC + 67= 180
Subtract 67 on both sides
2BAC = 113
Divide by 2 on both sides
BAC = 56.5
