9. Observe the picture and answer the questions

\(ABC\) and \(ADE\) are two similar triangles.

 

 

1. The perimeter of two similar triangles, \(ABC\) and \(ADE\), are 40 \(kms\) and 24 \(kms\). If one side of \(\triangle ABC\) is 6 \(km\), then the corresponding side of \(\triangle ADE\) is 2.61.64.63.6 \(kms\).

 

2. If \(\angle ADE = 57^{\circ}\) and \(\angle C = 70^{\circ}\), then the measure of \(\angle A\) is
