Question 74475: I have a question-
what equation do I use to work out the angles in a right angled triangle if there is a 5.6m line extending up the y axis and a 3.6m line extending along the x axis - both at a right angle to each other. There is an angled line from the top of the 5.6m line to the end of the 3.6m line. The angle i'm after is between the top of the 5.6m line to the line extended to the end of the 3.6m line.??? If you could help me out it would be great!!!

Question 75884: Please help me
tan(3x)+1={square root(2)}sec(3x)
so far i have tried:
(tan(3x)+1)^2=(sq rt(2))^2(sec(3x))^2
tan^2(9x^2)+1^2=2sec^2(9x^2)
tan^2 +1=2sec^2
tan^2+1 = sec^2
