Answer:
1/3
Step-by-step explanation:
To find the scale factor write a ratio from the side length of the small triangle to a corresponding side length of the large triangle.
C'B' has the distance 3 units and CB has the distance 9 units.
The ratio then is 3/9 = 1/3. So the scale factor is 1/3 because it is shrinking the larger triangle to the smaller as shown by the ' marks on the letters.
Answer:
20 cm
Step-by-step explanation:

1. Multiply the actual depth my the scale factor of 1/15.
2. Multiply the resulting depth after multiply by the scale factor by the conversion factor of meters to centimeters.
So basically 42=x times 64 or 42=64x where you want x to be represented as a fraction so just don't simplify as much
42=64x
divide both sdies by 64
42/64=64/64x
42/64=1x
x=42/64
simplify
42/64=21/32
the answer is 21/32 in simplest form
Answer:
A. 106 + 2x + 50 = 180
Step-by-step explanation:
A. 106 + 2x + 50 = 180. Correct.
B. 2x + 50 = 180. Incorrect. Angle is not a Straight Angle.
C. 2x + 50 = 106. Incorrect. That equals the first angle.
hope this helps.
