Answer:

The height of house is 8.48 m

Explanation:

Given as :

The angle of elevation to the top of house = 12°

The measure from base of house = 40 m

Let the height of house = h m

So,
$Tan\theta = (Perpendicular)/(Base)$

Or,
$Tan12^(\circ) = (Height)/(40)$

Or, 0.212 =
(Height)/(40)

∴ Height = 40 × 0.212 = 8.48 m

Hence The height of house is 8.48 m Answer
