Answer:
a) 306 cm b)270 cm
Step-by-step explanation:
Imagine a right angled triangle with height of pole = 120 cm and base = 102 cm.
Tanθ = opposite side to θ/Adjacent side to θ = 120/102. now use this to solve.
a) Height of pole = 360 cm. let x be length of shadow.
We know Tanθ = opposite side to θ/Adjacent side to θ = 360/x
120/102 = 360/x (∵ Tanθ = 120/102)
=> x = 3*102 = 306 cm.
a) Length of Shadow = 229.5 cm. let h be height of pole.
We know Tanθ = opposite side to θ/Adjacent side to θ = h/229.5
120/102 = h/229.5 (∵ Tanθ = 120/102)
=> h = 120 * 229.5 / 102 = 270 cm.
