Answer:
(i)
Answer:
(i)
Answer:
(i)
Solution:
Given: AC = c, AB = a, BC = b, FB = x
Area of ∆ABC = (1/2) x AB x BC
= (1/2) x a x b -(i)
= (1/2) x FB x AC
= (1/2) x x x c -(ii)
From (i) and (ii)
(1/2)ab = (1/2)cx
=> ab = cx
Option (i) is correct
Answer:
(a)
Solution:
Let the line 2x + y - 4 = 0, divide the line segment joining the points A(2, -2) and B(3, 7) in the ratio K:1. Let the point of intersection be M.
Then M{(3k + 2)/(k + 1), (7k - 2)/(k + 1)}
M lies on the line 2x + y - 4 = 0
2{(3k + 2)/(k + 1)} + {(7k - 2)/(k + 1)} - 4 = 0
6k + 4 + 7k - 2 - 4(k + 1) = 0
=> 6k + 4 + 7k - 2 - 4k - 4 = 0
=> 9k - 2 = 0
=> k = 2/9
Hence, the required ratio is 2:9
Solution:
-[{2(2) - 2 - 4}/{2(3) + 7 - 4}]
= -(-2/9)
= 2/9
or 2:9
