First, divide 17 by 5. You will get 0.2941176470588235. Now take the inverse cosine (cos^-1) of that decimal (0.2941176470588235). The raw answer is 72.895364823356 degrees, and the rounded answer is 73 degrees. Hope this helps.

Answer:

32 x p/100 = 40

(Solve for P)

Multiply by 100 on both sides

32x = 4,000

Divide by 32 to get:

X = 125%

(reason why you multiply by 100 is because opposite of division is multiplication and we multiply the number "100" because we always multiply the denominator to both sides when having a fraction so you can solve for p or whatever. And that means p/100 x 100 it means p because since p is not a known value we consider 1/100 x 100 = 1, a variable by itself means 1 so you could just put p by itself next to the number its multiplied by which is 32 so it would be 32p because your multiplying both and the opposite of that would be dividing by 32 on both sides because you are getting rid of the 32 so therefore you will be left with: X = 125)

El resto es 9.
