This question cannot be answered. You will have to give me the number to the square root. * * * * * a = ±sqrt(c^2 - b^2)
25x (square) plus 40 plus 15 equals 680.
2 + tansquareA + cossquareA
Plus or minus the base. If the base is X and you square it, you get X2. If you take the square root of that, you get Plus or Minus X. This is because X*X equals X2 and -X*-X also equals X2.
x = the square root of -1, an imaginary number written as a lower case italic i.
