Ө

1.1

= .785RAD or 45 

Our last step is a simple one—adding our Ө

1.1

and

Ө

1.2

values together:

Ө

1.1

+ Ө

1.2

= 76.96 

Ө

= 76.96 

And just like that, we have our final variable.

Thankfully, the entire process can be simplified into just two equations.

These might look just a little bit different, however. In order to simplify all our

equations into just two, a few things needed to happen:

• We have swapped c

2

for (x

2

+ y

2

) and c for √(x² + y²) to clean things up,

skipping the step needed to calculate the value of C independently.

• We have also jumped directly to the inverse form of our equations.

• Lastly, we swapped the ...
