nice ,it is the same but a simple standard equation.. can u post a picture with that 22degree and 97degree because i can't imagine the angle positon.. ..

can you give example?

thank you^^ you have nice tutorial... did you mean that this is the right formula? m1 = tan((tan^-1(m2))+given angle) or m1 = tan(theta + given angle) it is also the same with this formula tan(theta1-theta2)= ((m2-m1)/(1+(m1*m2)))?

i didn't understand your hint. the theta or angle are given and i know the high school inverse function.. i will thank you if you just let type the formula here or equate it to m1 and then i will think how it is derive.. if i didn't know i will ask you question^^

you mean tangent theta= slope?? so what's the specific formulai can use?

finding the slope?? how to find the slope of 1st line?. when 2nd line slope is given, angle between them is given, the intersection of the 2 lines are given also... any ideas? see this http://img87.imageshack.us/img87/1055/questionz.png
