Using the defects method, which of these relationships represents the Law of Cosines if the measure of the included angle betwee
n the sides a and b of ∆ABC is more 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 c
2 answers:
PLATO the answer is D area of square c2 = area of square a2 + area of squareb2 + area of defect1+ area of defect2 I just did this question
Cosine Law:
c² = a² + b² - 2 a b cos C
Answer:
C ) area of square c² = area of square a² + area of square b²
- area of defect 1 - area of defect 2
