Question

If the elevation of the sun changed from 30° to 60°, then find the difference between the lengths of
shadows of a pole 15 m high, made at these two positions​

Answer 1

Step-by-step explanation:

Length of pole = 15 m

Angle of elevation changes from 30∘ to 60∘

When the angle is 30∘

Length of shadow = Length of pole x tan30

Length of shadow = 15×tan30= 315

When the angle is 30∘

Length of shadow = Length of pole x tan60

Length of shadow = 15×tan60= 153

Now difference between the two distances = 153−315 = 345−15

= 103
