At 3pm, the length of the shadow of a thin vertical pole standing on level ground is the same as the height of the pole. a while later, the angle of elevation of the sun has decreased by 12° and the length of the shadow has increased by 95cm. determine the height of the pole.

The height of the pole is 175.97 ( approx )

Step-by-step explanation:

Let the height of the pole is x cm,

Also, let the angle of elevation of the sun to the pole at 3 pm is

Thus, by the question,

   ( at 3pm the height of shadow = height of the pole)

Again, according to the question,

When the angle of elevation is   ,

The height of shadow = x + 95,

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

0,0
