We first need to find the side opposite 30 degrees.

sin(30°) = h/8

sin(30°)•8 = h

4 = h, where h is the height of the triangle.

To find x, we continue to use trigonometry.

sin(45°) = 4/x

x = 4/sin(45°)

x = 5.6568542495

We could round this decimal number to two decimal places. When doing so, the value of x becomes 5.66 units.
