The attached image represents the triangle after it has been enlarged
<h3>How to enlarge the triangle?</h3>
The given parameters are:
- Scale factor, k = -1/3
- Center, (a,b) = (-1,2)
From the graph, the coordinates of the triangle are:
A = (-4,2)
B = (-4,-4)
C = (-1,-4)
The rule of dilation is calculated using:

So, we have:

A' = (0, 2)

B' = (0, 4)

C' = (-1, 4)

Answer:
25 yards
Step-by-step explanation:
radius is half of what the diameter is.
50 / 2 = 25
Answer:
37.8
Step-by-step explanation:
Set up a proportion using the values given in the diagram of similar triangles.
31.5/15 = x/18
Cross-multiply.
31.5(18) = 15x
Multiply.
567 = 15x
Divide both sides by 15.
37.8 = x
