We are given the following proportion and we are to determine whether it is a true proportion or not:
Finding the value of y:
So now we have
Checking if it is a true proportion:
Since the simplified fractions are equivalent, therefore the proportion is true.

Answer:
scale
Step-by-step explanation:
The scale is the ratio of the size of a model compared to the real object. A model is made to represent a real object that was too big (like building, bridge, car) or too small(bacteria, atoms, molecule). Having a model can help someone to visualize the real object easier. Scale can be represented as a percentage, or ratio.
The horizontal distance will be given by the trigonometry formula:
tan theta=opposite/ adjacent
theta=4
opposite=height=183 ft
horizontal=adjacent=a
thus
tan 4=183/a
hence
a=183/tan 4
a=2617.02 ft
