Ms. Durand has an obsession with Christmas. She is standing 8ft away from a 20ft Christmas Geometree. She wonders, "hmmm, what is the angle of elevation from myself to the star on the top of the tree?"

Answer:

68.20°

Explanation:

Using Pythagoras rule :

Tanθ = opposite / adjacent

Adjacent = 8ft

Opposite = 20

Tanθ = 20 / 8

θ = tan^-1(20/8)

= 68.198590

Hence, angle of elevation = 68.2°
