# How Total Station Works Mathematically?

I am working on some avr programming for a robot which can understand elevation of an object in distance for now that object is a mirror , i wonder how total station cameras works i mean mathematical formula

The only information you have is x and c in what formula i can get the elevation of B

If it's too basic to ask here sorry i am newbie in math , Thanks in advance

$$\beta =x\sin(c)$$ check : http://en.wikipedia.org/wiki/Triangle
Strings like "sin" are interpreted as concatenations of variable names and are therefore italicized. To get the right font and spacing for function names like $\sin$, you can use the predefined commands like \sin, or if you need a function name like $\operatorname{erf}$ for which there's no predefined command, you can use \operatorname{erf}. –  joriki Sep 20 '12 at 11:41
