Question

Simple geometry can compute the height of an object from the object's shadow length and shadow angle using the formula: tan(angleElevation) = treeHeight / shadowLength. Given the shadow length and angle of elevation, compute the tree height.

Answer 1

Explanation:

if Tan(angle of Elevation)= Tree Height/Shadow Length

Lets assume Tree height= x

shadow Length = 6

Tan(180)

therefore Tan (90)= x/6

Make X subject of formula x(Tree Height)= Tan 180 * 6 =8

x=8
