Question

What is the area of right angled triangle

Answer 1

Answer:

Angle of elevation and depression are always acute angles. If the observer moves towards the perpendicular line(Tower/ building) then angle of elevation increases and if the observer move away from the perpendicular line(Tower/ building) angle of elevation decreases. Hence, the value of AB is 1000(√3 - 1) m.

Answer 2

Area of right angled triangle =

$\frac{1}{2} \times b \times h$
