Answer:
XY= 6 feet
YZ= 4 feet
Perimeter = 18 feet
Explanation:
We see on both triangles the like sides are 24 feet on the big one and 8 feet on the little one
So we divide those 2 numbers to see how how many times bigger the bigger triangle is compared to the little one
24÷8=3
The big triangle is 3 times bigger then the smaller one
XY is similar to the side with 18 feet on th bigger triangle so we divide by 3
18÷3=6
XY=6 feet
Now for the next question to find YZ we use the similar side and divide by 3 which is the side with 12
12÷3=4
YZ=4 feet
Now to find the perimeter of XYZ we add all the sides we found together

feet
