Chapter 11, Problem 32CR

To determine

To find: lengths of the sides of $\Delta CDE$ .

Answer to Problem 32CR

Sides of $\Delta CDE$ are $10$ centimeters, $19$ centimeters and $25$ centimeters.

Explanation of Solution

Given information:

Sides of a $\Delta ABC$ are $20$ centimeters, $38$ centimeters, $50$ centimeters in length.

Scale factor $=k=0.5$

Given

Sides of a $\Delta ABC$ are $20$ centimeters, $38$ centimeters, $50$ centimeters in length.

Scale factor $=k=0.5$

Multiply each dimension $\Delta ABC$ of by the scale factor of $0.5$

First Dimension of $\Delta CDE$ is $20\times 0.5=10$ centimeters

Second Dimension of $\Delta CDE$ is $38\times 0.5=19$ centimeters

Third Dimension of $\Delta CDE$ is $50\times 0.5=25$ centimeters.

Therefore,

Sides of $\Delta CDE$ are $10$ centimeters, $19$ centimeters and $25$ centimeters.
