Question

if the altitude of the sun is 60⁰ the height of tower which casts a shadow of length 90m is​

Answer 1

Answer:

If the altitude of the sun is at 60°, then the height of the vertical tower that will cast a shadow of length 30 m is 30√3 m.

hope it's help you

Answer 2

Answer :-

Given :-

• Angle of elevation = 60°
• Length of shadow = 90m

Let the height of the tower be Ab i.e. h.

Therefore,

TanC = AB / BC

=> Tan60° = h/90m

$\sqrt{3} = \frac{h}{90} \: \: \: \: \: \: \: \: \: \: \\ = > h = 90 \times \sqrt{3} \\ = > 90 \sqrt{3} \: \: \: \: \: \: \: \: \: \: \:$

Hope the answer helps you.
