Solve for the value of x in simplest radical form. Remember to write square roots as SQRT.
Wow....what a skewed-not-to-scale looking drawing..... if that angle is really 45 o then the lower right angle is also 45o
the hypotenuse of the 3-4 triangle is 5
sin45 = opposite/hypotenuse = x / 5
sqrt 2/ 2 = x/5
x = 5 sqrt(2) / 2 or 5/2 sqrt 2
