Answer:
a = 17
Step-by-step explanation:
Because all the lines are congruent (same length) as indicted by the lines, this means that every angle is the same.
180 ÷ 3 = 60
So every angle is 60°
This also means that:
4a - 8 = 60
Isolate the 4a by moving the -8 over to the other side, making it a +8:
4a = 60 + 8
4a = 68
Now simply divide both sides by 4 to get the value of 1a:
a = 17
<h3>So a = 17 </h3><h3 /><h2>Hope this helps!</h2>
If the ratio of a model train to a real train exists 1:3 and the real train exists 12 feet then the model train exists 3 feet long.
<h3>How to estimate the ratio of the model train?</h3>Given that the model train contains a scale of 1: 3 and the real train exists 12 feet tall.
The ratio indicates how many times one number has another number.
A ratio exists as the relationship in quantity between two things.
It conveys the quantity of one thing in words of another.
The ratio of a model train to a real train exists at 1 inch :3 inches.
Height of model train = 12 1/4
Height of model train = 3 inches
Therefore, the ratio of a model train to a real train exists 1: 3 and if the real train exists 12 feet then the model train exists 3 feet long.
