The value of x is 8.5 cm
The complete question is in the image
The given parameters are:
y = 12 cm
[tex]\theta = 45^o[/tex]
The value of x is calculated using the following sine ratio
[tex]\sin(\theta) = \frac xy[/tex]
This gives
[tex]\sin(45^o) = \frac x{12}[/tex]
Multiply by 12
[tex]x = 12 * \sin(45^o)[/tex]
Evaluate
x = 8.5
Hence, the value of x is 8.5 cm
