Question

the height of a tower is 400m when the altitude of the sun is 30°, then the length of its shadow will be?​

Answer 1

Given :

• AB = 400m = height of tower
• ∠A = 30°
• ∠B = right angled = 90°

To find : BC = Shadow of tower

Solution :

• Tan A = oppodite to ∠A / adjcent to ∠A
• Tan 30° = BC / 400
• 1/√3 = BC / 400
• 400/√3 = BC
• BC = 400√3/3 m = 230.67 m = Shadow of Tower
