One idea he came up with was a mathematical equation that's used all the time, for example in architecture ... of two sides equals the square of the hypotenuse (the longest side).

label the sides on the triangle decide which ratio to use (SOH CAH TOA) substitute the correct information into the ratio rearrange to find '\(x\)' solve using your calculator making sure your ...

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 ...
