Question

Answer 1

Since ABC is similar to XYZ we know that their corresponding sides are proportional which means that AB/XY=BC/YZ=CA/ZX=4/3

Using given information we have that:

20/XY=36/YZ=24/ZX=4/3

Combining 1st and fourth we have: 20/XY=4/3. Using cross multiplication property you get 20 · 3= 4· XY.

Solving for XY we have: XY=15.

Similar you can find rest of two sides.

Hope it helps
