Dear Student
We apologize for the slight misprinting in the question..
In denominator...in place of 1+atan^2(30)...eliminate a...rest is fine
But, if you would like to solve the question on the basis of original data, then the answer would be
a=3/7
You can solve this in whichever way you want
Our main objective is to introduce you to these types of questions
Keep Learning
Thanks & regards
