Question

If the length of the shadow of a pole of height 5m at a certain time of the day is 5.5m, find the height of another pole, the shadow of which at the same time is 3.52m long.​

Answer 1

Answer:

3.872

Step-by-step explanation:

BECAUSE IN THE FIRST CASE WHE CAN SEE THAT THE SHADOW OF THE POLE IS 5M BUT AFTER A CERTAIN TIME IT BECAME 5.5M

THAT MEANS IT WAS INCREASED BY THE 10% OF THE GIVEN NUMBER.

LIKE THAT THE NUMBER 3.52 SHOULD BE INCREASED BY ITS 10%

THERE FORE, THE ANSWER = 3.52×10/100

= 0.352

THEN WE SHOULD ADD THE 3.52 AND THE

0.352

3.52+0.352=3.872

Answer 2

Answer: 3.2 m

Step-by-step explanation:

let x be the actual height of the pole

we know that tan Ф = perpendicular/base

tan Ф = 5/5.5

∴ Ф = tan inverse  5/5.5

tan (tan inverse 5/5.5) = x/3.52

x= 3.2 m
