Question

if the height of a vertical pole is equal to the length of its shadow on the ground, find the angle of elevation of the sun

Answer 1

Let the height of the pole be x

∵ height of the pole = length of the shadow

∴ the length the shadow = x

let the angle of elevation of the sun be Ф

then.

tanФ = x/x

or, tanФ = 1

or, tanФ = tan45° .......................(∵ tan45° = 1)

∴ Ф = 45°

Answer 2

Answer:

tan 45°

Step-by-step explanation:

h/h =1 =tan 45°
