The measure of the angle BAC is 55 degrees
Lines and angles
An angle is the point where two lines meet. From the given diagram, the sum of the angle in the triangle BAC is 180 degrees
Determine the measure of <BCA
<BCA = (40+55)
<BCA = 95 degrees
Determine the measure of <BAC
<BAC = 180 - (95+30)
<BAC = 180 - 125
<BAC = 55 degrees
Hence the measure of the angle BAC is 55 degrees
