Hi there.. there are many ques and also you have not specified.. I am assuming that you are talking about last one.. For this you just need the formula of tan(A+B+C)=(tanA+tanB+tanC-tanAtanBtanC)/1-tanAtanB-tanAtanC-tamBtanC.. Just put all values and it will come out to be 1.

Dear Student,
In the above attachment, there are several questions & unfortunately, since you have not mentioned the question number, it is pretty difficult to understand which question to answer and of course answering all of them is going to be a waste of time so please comment below which question to answer so that I can help you. 
 
Thanks!
