The side lengths of triangle ABC are 10, 14, and 16. The side lengths of triangle A′B′C′ are 35, 49, and 56. Identify the scale factor of a single dilation between the preimage ABC and image A′B′C′.(1 point)Responses3.53.53327Start Fraction 2 over 7 End Fraction5.6
The scale factor of a single dilation between triangle ABC and triangle A'B'C' is 3.5 (or 3.53 when rounded to two decimal places).
This can be found by dividing the side length of triangle A'B'C' by the corresponding side length of triangle ABC:
35/10 = 3.5
