All we can determine from the information that you have given us is that
yz should be proportionally related to bc, because their triangles are similar.
Answer:
6
Step-by-step explanation:
I counted
For this case we have:
Be a function of the form 
Where:

If we want to find f (-2), we substitute
, then:

Since we have a negative root, the result will be given by complex numbers. By definition:

So:

Answer:

Answer:
Area of shaded region = 134.13 square feet

Answer:
67.97
Step-by-step explanation:
let AC be length of ladder and BC be distance between ladder and wall and angle be theta
Now,
costheta=BC/AC
THETA =COS^-1(3÷8)
THETA=COS^-1(0.375)
THETA=67.97 DEGREE
