The length of the model as described in the task content would be; 23 inches.
<h3>What is the length of the model?</h3>
According to the task content, it follows that for every 25 feet measure of the actual ship length, the representation is 1 inch on the model.
On this note, for 575 feet length of the actual ship, the length of the model is; 575/25 = 23 inch.

How big are the other rooms
There are 77,600,000 pet cats rounded to the nearest hundred thousand because of the rule that if its over 5 round up under round down and 5>2 so the answer is 77,600,000
Given : tan 235 = 2 tan 20 + tan 215
To Find : prove that
Solution:
tan 235 = 2 tan 20 + tan 215
Tan x = Tan (180 + x)
tan 235 = tan ( 180 + 55) = tan55
tan 215 = tan (180 + 35) = tan 35
=> tan 55 = 2tan 20 + tan 35
55 = 20 + 35
=> 20 = 55 - 35
taking Tan both sides
=> Tan 20 = Tan ( 55 - 35)
=> Tan 20 = (Tan55 - Tan35) /(1 + Tan55 . Tan35)
Tan35 = Cot55 = 1/tan55 => Tan55 . Tan35 =1
=> Tan 20 = (Tan 55 - Tan 35) /(1 + 1)
=> Tan 20 = (Tan 55 - Tan 35) /2
=> 2 Tan 20 = Tan 55 - Tan 35
=> 2 Tan 20 + Tan 35 = Tan 55
=> tan 55 = 2tan 20 + tan 35
=> tan 235 = 2tan 20 + tan 215
