Answer:
x=12.5
y=3.2
z=6
Step-by-step explanation:
Both of the shapes are similar, which means it's the same shape but one has sides that are bigger than the other. The ratio is 10:4 as you can see by the very left side of both shapes. So, basically the bigger shape has sides that are 2.5 times bigger than the smaller shape. So, 5*2.5=12.5 to get x, 8÷2.5=3.2 to get y, and 15÷2.5=6
