Answer:

3.14 cm

Explanation:

∆DEG is similar to ∆DFH, so

DE/DG = DF/DH

3.0/2.3 = (3.0 + 4.1)/(2.3 + x)

3.0/2.3 = 7.1/(2.3 + x) Divide each side by 7.1

2.3/3.0 = (2.3 + x)/7.1 Multiply each side by 7.1

(2.3 × 7.1)/3.0 = 2.3 + x Subtract 2.3 from each side

x = (2.3 ×7.1)/3.0 – 2.3

= 5.443 – 3.0

= 3.14 cm

Check:

3.0/2.3 = (3.0 + 4.1)/(2.3 + 3.14)

1.304 = 7.1 /5.44

1.304 = 1.305

The numbers check to the nearest hundredth.
