final correct answer

Answer 1

Answer:

firstly focus on figure

1. this is isosceles triangle
2. angle B is 44 degree because it's half angle is 22

so let angle BAC and angle BCA be x

area of triangle =sum of all angles

sum of all angles of a triangle is 180 degree

44+x+x=180

2x=180-44

2x=136

x=136/2

x=68

so angle BAC is 68 degree
