Question

Triangle abc has been dilated about point a by scale a factor of 1/3

Answer 1

Answer:

The answer is the option B. $10, 16, 13$

Step-by-step explanation:

We know that

The scale factor is equal to $\frac{1}{3}$

so

To know the lengths sides of triangle A'B'C'. multiply the lengths sides of triangle ABC by the scale factor

$A'B'=AB*\frac{1}{3}$ -----> substitute $A'B'=30*\frac{1}{3}=10\ units$

$A'C'=AC*\frac{1}{3}$ -----> substitute $A'C'=39*\frac{1}{3}=13\ units$

$B'C'=BC*\frac{1}{3}$ -----> substitute $B'C'=48*\frac{1}{3}=16\ units$

therefore

The answer is the option B

Answer 2

The answer is 10, 16, and 13
