Answer:

Step-by-step explanation:
-In a right triangle, the Sine of the base acute angle is usually given as:

-In ΔVWX,, VX is the opposite and WV the hypotenuse.
-Therefore, sine of ∠Wis calculated as;

Hence, sine of ∠W is given represented by the ratio

Answer:
3
Step-by-step explanation:
<u>1) Find two corresponding lengths between the image and the pre-image</u>
Pre-image (bottom side) = 3 units
Image (bottom side) = 9 units
We can use any corresponding lengths for this step.
<u>2) Divide the length of the side from the image by the length of the side from the pre-image</u>
9 units ÷ 3 units
= 3
Therefore, the scale factor of the dilation is 3.
I hope this helps!
