@Alan @Sir Emo @CPhill,guys sorry for the late reply, and yeah i also arrive at the same aswer, mine is 11.098 to be exact, my solution is a little bit longer(though it's pretty much the same as your's) and i dont have a pc to write it down like you guys (im using my mom's ipad) so it might confuse you guys if i wright it here manually

well i decided to join when i found out about this site, because i want to learn more and also help others if i know how to answer their problem

that you very much guys , im a little confused but i'll try to understand it(im kinda slow in math) 

@Melody ohh right,(d**n i really need my eye glasses) i didnt notice it was on the 1st reply 

thank you very much alan for aswering my question(im sorry i didnt notice you had another approach on the 1st problem and yeah that is the right one) , but i got confused on how you wrote the second problem is y= squaroot of 1+ tan^2 (theta) , is it just equal to your y= squaroot of 1+ tan (theta) ^2?
