Question

 

ABC is a triangle such that

         

If AB and C are in A.P. then the value of AB and C are

Solution

Correct option is

45o, 60o, 75o

 

We know that in a triangle A + B + C = 180o  

and    2B = A + C                  (As A, BC are in A.P.)

          3B = 108        or B = 60o

Now ‘’ be the common difference between AB and C.  

  

  

  

    

  

  

 as a cannot be less than ‘0’ and
