Question

Help me :(

Answer 1

The perimeter of the larger triangle is 69, so you know
\[69=24+24+x\]
What's \(x\)?

Answer 2

x= 21

Answer 3

Once you find that, the question wants you to find \(y\):

To do that, you set up a ratio equation; this is true because the triangles (look like they) are similar:
\[\frac{x}{y}=\frac{24}{8}\]
Solve for \(y\).
