Use trigonometry here.
sinx = opposite side/ Hypotenuse
so, sinx = 4/5 = 0.8
x= sin^-1(0.8) which is 53.13
Hope it helps
3(x + 4) = 3x + 4
3x + 12 = 3x + 4
3x - 3x = 4 - 12
0 = -8 (incorrect....no solution)
little tip ...
if it ends with a variable equaling a number, like x = 2 or y = 4, then there is 1 solution.
if it ends with something unequal with no variable, like 0 = -4 or 5 = 7, then there is no solution.
if it ends with something equaling with no variable, like 2 = 2 or 5 = 5, then there is infinite solutions.
