Using the properties of similar triangles, create a ratio showing the relationship between △ABC and one of the smaller triangles. Cross multiply the ratio to derive a simplified equation. Do not use the altitude you drew (segment f) as part of the equation.
then
Now use the properties of similar triangles to write the relationship between △ABC and the other similar triangle you drew. Cross multiply the ratio to derive a simplified equation. Do not use the altitude you drew as part of the equation.
