When it comes to calculating more complex adjacent angle problems, it will be helpful to identify opposite angles formed by the same line segments. For example, let's say six adjacent angles add ...

The cosine (cos) function takes the angle Ɵ and gives the answer to adjacent ÷ hypotenuse (in this example, 16/32). cos⁻¹ is the inverse function of cos. The cos⁻¹ function takes the ...
