May anyone please teach me how to solve the two questions in the photo attached? It would be much appreciated thank you!

What is the measure of \(\overline{CE}\)?

What is the measure of \(\overline{CE}\)?

since its a square so CB=DC=35cm

CE=(3/(3+2))x35cm=21cm

ED² = CE² + CD² → ED = ?

tan(Θ) = CE/CD = ?

Can you demonstrate that \(\triangle CDE\) and \(\triangle BEF\) are similar?
