bro fig banane ke baad
apply similar traingle concept in ABM & BMC
u will get the ans
usse bhi nhi smjh aa rha :banghead:

@JS-M
u will get the following eqns after applying similar trian theorem
a/6 = 6/a+5

solve for a

Find the area of the triangle formed by the lines whose equation are 2y - x =5, y + 2x =7 & y-x =1?
1934
The value of (rt5+rt3)[3rt3/(rt5+rt2) - rt5(rt3+rt2)] is?

yaar answer 3/10 de rakha h
iska koi short cut hota hai kya???

yr i applied area concept.........r m nt getting by which property u made them similar...and what aftr similarity...??

Bro just find the three point of intersection
these will be coordinates of traingle

then apply formula to find the area of trian when coordinates r gvn

bhai woh 3 points of intersection main
in 3 equations ko solve kar k nikala h
ab yaar short-cut nahi aate h bilkul
main acse woh 3 points of intersection ka hi h

bro 3/10 ans hai

points are...... (3,4 ) (9/5,17/5) (2,3)

Bro only shortcut possible is
if u plot the lines on axis & chk if they form right triang
But if they are not forming then ur tym is wasted & u will hav to resort
back to this mthd onlly
so do lyk this only find the coordinates
then apply the matrix formula

This is shortest as per me

r u sure ki en points se 3/10 ayega......m getting 6/5 by matrix method...

yeah bro ......3/10
Chk again

A circle passes through the vertex C of the Rectangle ABCD and touchs its side AB and AD at P and Q respectively. If the distance ofrom C to the line segment PQ is equal to 6 cms. , then what is the area of the Rectangle ABCD?

a) 15 b) 36 c) 24 d) 18
