# Mast

Mast has 17 m long shadow on a slope rising from the mast foot in the direction of the shadow angle at angle 9.3°. Determine the height of the mast, if the sun above the horizon is at angle 44°30'.

Result

h =  19.23 m

#### Solution:

$h = 17 \cdot ( \cos(9.3^\circ)\cdot \text{tg}(44.5^\circ) + \sin(9.3^\circ) ) = 19.23 \ \text{ m }$
