48 feet
Divide 858 by 18 to get 47.6 > simplify > 48 feet
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
Answer:
A
Step-by-step explanation:
Note that for (3, 2) → (5, 3)
The x- coordinate of the image is 2 more (+ 2) than the original and the y- coordinate of the image is 1 more (+ 1) than the original, that is
(x, y ) → (x + 2, y + 1 ) ← rule to obtain image, hence
(2, 4 ) → (2 + 2, 4 + 1 ) → (4, 5 ) → A
Answer:
<h2>D</h2>
Step-by-step explanation:
The shape we see is a kite.
The measures of the triangles must add to 180°.
27 + 90 + x = 180°
117 + x = 180°
x = 63°
3 = 63°
We can also solve for 1 and 2. 2 is a right angle so 90° and 1 is a reflection of the 27° angle on the other side, so it also is 27°.
1 = 27° 2 = 90° 3 = 63°
I'm always happy to help :)
