1. A ladder, leaning against a wall, makes an angle of \(60^°\) with the horizontal. If the foot of the ladder is \(2.7 m\) away from the wall, find the length of the ladder.
Length of the ladder \(=\) \(m\)
2. In figure, a tower \(AB\) is \(14 m\) high and \(BC\), its shadow on the ground, is \(14\sqrt{3}\)m long. Find the sun’s altitude.

Sun's altitude \(=\)\(^{\circ}\)
