$|DE|=5\\|\angle EDF|=55^o\\|FE|=?\\\\tan|\angle EDF|=\frac{|FE|}{|DE|}\\\\tan55^o\approx1.4281\\\\therefore:\\\frac{|FE|}{5}\approx1.4281\Rightarrow|FE|\approx1.4281\times5=7.1405\approx7.1$

5 Trucks

Step-by-step explanation:

Since each truck goes on three trips, we multiply the 300 dollars each truck gets per trip by 3 to find the total amount of money each truck makes each week, which is 900. If Lennox made 4500 dollars in one week, at 900 per truck, 4500/900= 5 trucks.
