1(a) x0=1
Verification
Taking log both sides
0.logx=log1
Which is true.Hence the given relation is also true.
Help me prove that
a} xo=1
b}If two triangles are equiangular ,then their corresponding sides are proportional.

36Too easy Arvind... i didn't see it before
1> x0 = x(m - m) = xm.x-m = xm/xm = 1
or, x0 = 1 Done..!!
2> IF two triangles are equiangular that means both of them are similar by (AAA criterion) and so, their sides will be proportional (by the definition of similar triangles)
well one more thing ....
Did you know that,
In two triangles if two corresponding sides are equal and angles excluding them are equal then both of them are congruent.
i.e., Did u know bout the SSA criterion?
well it is... check for my previous posts.... u'll get the proof !!
sorry but i added something more than u asked :D
