In a triangle ABC , A + B + C =k What is the value of A B C ?
Options
- A0.5 k
- B1 k
- C3 k
- D1 k^3
Correct answer
B. 1 k
Step-by-step solution
In ABC , A + B + C = Taking both side, we get aligned & (A+B+C)= =0 & A+ B+ C- A B C 1- A B- B C- C A =0 & A B C= A+ B+ C & A B C= 1 A+ B+ C & = 1 K aligned
