Please Help, Horizontal Lengths!!!
I'm new here so big hi to everyone.
O.k. I have an assignment question here, its the last of 5 and i'm chuffed because i've solved all the rest but now my heads a bit broken.
this is the last question:
"three lines on a site form a triangle on plan. the HORIZONTAL lengths were measured and found to be 20.988, 38.011 and 25.101.
Determine the angles etc."
I can answer the question no prob, but i'm being cautious here, the words horizontal indicates that these are not the lengths of the lines of the trianlge. they may well be and i'm just being paranoid but this seems a trick question to me.
so my question is, can i find the length of an angled line from the horizontal length alone?
I'm sure its impossible because i have no angles, with the angle its easy, additionally, i have no vertical component in order to find the angles using tan..........im lost.
so guys, any thoughts or am i just reading to much into the question?
