Answer:
Using the AA similarity postulate, you can determine that these triangles are similar.
Step-by-step explanation:
All three triangles are right triangles, so they all have 90° angles.
Angle B is present in the large and small triangle. Therefore, you know those 2 triangles are similar. You can also prove that angles A and C are the same.
A and B are complementary angles in the large triangle and the same with B and C in the small one. Since B ≅ B by Reflexive Property, A and C must have the same angle measurement since they are complements of the same angle.
I would say that the r = -0.24 since the correlation is very low, it has a slightly negative trend but since there is no strong correlation between the variables, the answer that is closest to 0 is your best bet (-0.24)
First you are going to distribute and you are going to get 8c-72=12c-72-4c.
Next you are going to combine like terms you get 8c-72=8c-72.
Then move the Varible to one side and solve for the Varible you should get c=0
