Answer:
No, because all the moon phases last 28 days. 21 days is not enough time to observed them.
Step-by-step explanation:
Find the slpes
if they are, then they are paralell
y=mx+b
m=slope
y=2/3x-17
slope=2/3
the other slope
in form ax+by=c
slope=-a/b
4x-6y=-6
-4/-6=2/3
2/3=2/3
the lines aer paralell
The proportion that could be used to find the value of x is 3/x= x/11
<h3>How to determine the proportion?</h3>
The complete question is added as an attachment
From the attachment, the common side length between both right triangles is x
While the other sides are adjacent sides.
This means that the proportion is:
3/x= x/11
