An eagle is flying at a speed of 155 \(km/h\). If the angle of elevation of an eagle from a point on the ground is 45\(^{\circ}\). After 19 seconds, the angle of elevation changes to 30\(^{\circ}\), then the altitude of the eagle from the ground is ?. (Use \(\frac{1}{\sqrt{3}} = 0.577\))
Solution:
The altitude of the eagle from the ground is \(km\)
