Triangle def is similar to triangle ghk. what is the value of df if gk is 3.4 inches, ef is 2.25 inches, and hk is 9 inches?

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8
