Mrs Kebeh stands at a distance of 110 m away from a building of vertical height 58 m. If Kebeh is 2 m tall, find the angle of elevation of the top of the building from her eye.
\(27^0\)
\(28^0\)
\(20^0\)
\(26^0\)
Explanation
Tan\(\theta = \frac{opp}{adj}\)
Tan\(\theta = \frac{56}{110}\)
\(\theta = tan^1(0.5091)\)
therefore, \(\theta\) = 27° ( to the nearest degree)
