The fact that the pentagons are similar means that there is a proportional relationship between corresponding sides. Likely side AB is intended to correspond to side FG, so side HI will correspond to side CD.

(Side of FGHIJ)/(Side of ABCDE) = HI/CD = FG/AB
HI/5 = 30/10 = 3    (put the numbers into the above equation)
HI = 5*3 = 15    (multiply the equation by 5)

Side HI is 15 units long.
