Using the defects method, which of these relationships represents the Law of Cosines if the measure of the included angle between the sides a and b of ∆ABC is more than 90°? A.
area of square c2 = -area of square a2 − area of squareb2 + area of defect1 + area of defect2
B.
area of square c2 = area of square a2 + area of squareb2 + area of defect1 − area of defect2
C.
area of square c2 = area of square a2 + area of squareb2 − area of defect1 − area of defect2
D.
area of square c2 = area of square a2 + area of squareb2 + area of defect1+ area of defect2
E.
area of square c2 = area of square a2 − area of squareb2 + area of defect1 − area of defect2
