Using the defects method, which relationship represents the Law of Cosines if the measure of the included angle between the side

s a and b of ΔABC is less than 90°?
A) area of square c2 = -area of square a2 − area of square b2 + area of defect1 + area of defect2
B) area of square c2 = area of square a2 + area of square b2 + area of defect1 − area of defect2
C) area of square c2 = area of square a2 + area of square b2 − area of defect1 − area of defect2
D) area of square c2 = area of square a2 + area of square b2 + area of defect1 + area of defect2
