Sanjay is fond of gardening. He purchases a beach house and pots plants in the shape given below.
Here, \(CD\) \(=\) 1.3 \(m\), \(BC\) \(=\) 5.2 \(m\), \(DE\) \(=\) 1.8 \(m\) and \(\angle ACB\) \(=\) \(\angle ECD\).
1. What are the two similar triangles formed in the figure?
2. What is the similarity criterion applied in the figure?
3. What is the ratio between the two given similar triangles?
4. If \(\angle BAC\) \(=\) 40\(^\circ\), find \(\angle DEC\).
5. What is the length of \(\overline {AB}\)?
