Please help!!!!!!!!!

Answer 1

The answer would be x=245 cm

Answer 2

Answer:

3.14 cm

Step-by-step 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.
