Answer:
4 units
Step-by-step explanation:
Since the two triangles are similar, their sides are proportional. To find the length of the side, you need to use the distance formula:
The coordinates you will use are (0, 0) and (-4, 0) because they correspond to points X and Y in Triangle PQR:
Then, simplify everything under the radical:
Finally, take the square root of 16:
= 4
