I don't understand what you're asking me. Can you write in complete sentences?

Here is a small bit of a hint: \(\displaystyle \L
\theta = \arctan \left( {\frac{{4.3}}{x}} \right) - \arctan \left( {\frac{{1.8}}{x}} \right)\).

Further hint:
forget about the 1.2 bottom part;
work with right triangles with legs (1, 4.3), (2, 4.3) .... (8, 4.3)
note: the 4.3 is from 2.5 + (3 - 1.2)

cool thanks! i got it ..but how do i convert from a degree to radion?

degrees = radians*180/pi
radians = degrees*pi/180
A circle has either 2*pi radians or 360°
