2. Calculate and input Theta by subtracting Degree “A” (found by the
Law of Cosines) from known angle of 90° (in this case, the Triangles
form a Right Triangle):
9 0 – Ç 9 /_ A 83.83727°
= 6.162732 (Theta θ)
p /_ Ø 6.162732°
3. Recall stored “b” and input as “r”:
® 5 = d R 2096.

4. Calculate “x”:
R X 2083.887

5. Calculate “y”:
r Y 225.0112
