The word is CALCULATE. ( to determine or ascertain by mathematical methods; compute
Let angle = x
sinx = 43.2/72.5
=> x = 36.57 degrees
Y = -5x -5
To check, we can insert 0 for y and -1 for x
0 ? (-5X-1) - 5
0 ? 5 - 5
0 = 0
So yes, the equation is correct
Is the answer 5r-1? I'm not sure tho sorry if it's wrong!
