Find 20% of 11.45
=2.29
Therefore I saved $2.29
Step-by-step answer:
Given an enlargement from preimage (ABC) to image (A'B'C').
Need to find scale factor.
Solution:
Scale factor = linear size of image / linear size of preimage.
From the accompanying diagram, we see that
L(preimage) = AC = 4 units
L(image) = A'C' = 12 units
Therefore
Scale factor = L(image) / L(preimage) = 12 / 4 = 3
Let's split it into rectange and tringle
BC= 2.1+ sqrt(3.2^2 - 1.9^2) = 4.67

Answer:
17
Step-by-step explanation:
a^2 + b^2 = c^2
a^2 = 8^2 = 64
b^2 = 15^2 = 225
64 + 225 = 289
c^2 = 289
c = Square root of 278
c = 17
