The scale factor that was applied to figure A to produce figure B is: 11/3 = 3.67.
<h3>How to Find the Scale Factor of a Dilation?</h3>The ratio of the corresponding dimensions of the image to the preimage gives the scale factor of any dilation.
That is:
Scale factor = dimension of image (new figure) / corresponding dimension of pre-image (original figure).
The scale factor that was applied to figure A to produce figure B = dimension of figure B / corresponding dimension of figure A.
A dimension of figure B = 33
Corresponding dimension of figure A = 9
Therefore, we would find the scale factor as shown below:
The scale factor that was applied to figure A to produce figure B = 33/9
= 11/3 = 3.67
Therefore, the scale factor that was applied to figure A to produce figure B is: 11/3 = 3.67.

First, split the triangle into half.
So the angle 38 becomes 38/2=19.
So we know two angles in the triangle:
One is 19 degrees.
The other one is 90 degrees (marked red).
The angles in a right-angled triangle add up to 180 degrees.
So to find the x angle, we calculate it by:
180 - (90+19) = 71
(the sum of three angles) - (the sum of the two known angles) = unknown angle
So x = 71 degrees.
