Based on the change in the perimeter, the scale factor of the dilation is 3.5.

The scale factor of the dilation refers to the number of times the triangle was dilated such that it went from 12 inches to 42 inches.

This dilation can be found as:

<em>= Increased perimeter / Original perimeter </em>

Solving for it would give:

= 42 / 12

= 3.5

In conclusion, the scale factor of the dilation is 3.5.

A figure lies entirely in Quadrant I. The figure is reflected in the xx-axis. In which quadrant is the image?

FinnZ [79.3K]

The image would then be in quadrant 3 because say you "folded" the coordinate plane across the x-axis, then the point attached onto the other side of the plane, the point would be in the 3rd quadrant.

Determine the shortest segment in △ PQS and △ QRS. Remember that a segment is named by its endpoints (two letters).

irinina [24]

Answer: QS and QR are the shortest segment of the triangle ΔPQS, and ΔSQR respectively.

Step-by-step explanation:

Since we have given that

ΔPQS, and ΔSQR,

Consider, ΔPQS,

As we know that " the length opposite to the largest angle is the shortest segment."

So, According to the above statement.

$\angle QPS=63\textdegree\\\\\text{So, QS is the shortest segment of this triangle}$

Similarly,

Consider, ΔSQR,

Again applying the above statement, we get that,

$\angle QSR=75\textdegree\\\\\text{ So, QR is the shortest segment of this triangle}$

Hence, QS and QR are the shortest segment of the triangle ΔPQS, and ΔSQR respectively.
