two sides of triangle are 50m and 8m, third side is n, find out the n??
a)392 b)390 c) 398 d) 395

• Two sides of triangle are ln(50) and ln(8), third side is ln(n). Find out the number of possible values of n?
  
  Ans:-
  
  Sum of two sides of a triange is always greater than the third side
  
  case 1:
  
  So, ln(50) + ln(8) > ln(n)
  
  => ln(50x8) > ln(n) ( ∵ log (a) + log(b) = log(ab) )
  
  => 400 > n
  
  i.e. n < 400
  
  logax is defined for x > 0. So, n will be greater than 0
  
  So, 0 < n < 400
  
  case 2:
  
  So, ln(50) + ln(n) > ln(8)
  
  => ln(50n) > ln(8) ( ∵ log (a) + log(b) = log(ab) )
  
  => 50n > 8
  
  i.e. n > 4/25
  
  case 3:
  
  So, ln(8) + ln(n) > ln(50)
  
  => ln(8n) > ln(50) ( ∵ log (a) + log(b) = log(ab) )
  
  => 8n > 50
  
  i.e. n > 25/4
  
  
  
  Combining results from case 1, case 2 and case 3 we get:
  
  25/4 < n < 400
  
  So, range of integral values of n satisfying the above condition is: 7 ≦ n ≦ 400
  
  Hence no of integral values of n are: 393

• difference of two sides< 3rd side< sum of two sides
  sum=ln(50)+ln(8)=ln(400)
  difference=ln(50)-ln(8)=ln(25/4)=ln(6.2)
  so, ln(6.2)

• the answer would be 392
  
  the range would be from 25/4 to 400 25/4
