Hey there! :D
If you already know that two triangles are congruent, (which is given)
then any other part of the triangle can be proved congruent by CPCTC.
Congruent Parts of Corresponding Triangles are Congruent.
I hope this helps!

Answer:
Step-by-step explanation:
if you need help let me know
Let's start by understanding that the graph is a linear line. We have a common difference if 4.5 for every 10x we have more.
We can start by finding the gradient, using rise over run. Let's take (10, 4.5) and (20, 9)
Our rise is 9 - 4.5 = 4.5 and our run is 10. Then, our gradient becomes 4.5/10 = 0.45
Now, we can substitute points using the point-slope form.
y - 4.5 = 0.45(x - 10)
y - 4.5 = 0.45x - 4.5
Hence, our line becomes y = 0.45x and you can verify by substituting in points from the table.
