If ( , ) is the orthocentre of the triangle with the vertices (2,2),(5,1),(4,4) , then + =
Options
- A6
- B5
- C5 2
- D7 2
Correct answer
A. 6
Step-by-step solution
A (2,2), B (5,1), C (4,4) Slope of A B= 1-2 5-2 = -1 3 Equation of CG aligned & y-4=3(x-4) & 3 x-y=8 aligned Slope of A C= 4-2 4-2 =1 Equation of BF y-1=-1(x-5) x+y=6 (ii) Solving (i) and (ii) we get (x, y)=( , )= ( 7 2 , 5 2 ) + = 12 2 =6
