For this case, we observe that the triangles are similar. We observe that the triagnules have three equal angles. Therefore, to find the value of x we can use the following relationship: [tex]x / 15 = 5/12
[/tex] Clearing x we have: [tex]x = (5/12) * (15)
x = 6.25[/tex] Answer: The value of x is given by: x = 6.25
