4 = - 3(2) + c
4 = - 6 + c
c = 10
y = - 3x + 10
You have to do 0.09 x 378.00 and you will get 34.02.
So basically the answer is 34.02
The calculator returns an error as the answer for the inverse sine of 1.055 because the acceptable range for sine is only from 0 to 1.00 in which 1.055 is clearly greater than. This is also the same as for the cosine values.
You could add them on a number line or count on your fingers.
