Question

from the top of a tower, a man finds that the angle of depression of a car is 30°if the car is at a distance 40cm from the tower? find the height of the tower

Answer 1

Answer:

Step-by-step explanation:IN TRIANGLE ABC,

LET <A =30degree and <B= 90degree

AB is the tower

BC=40cm[distance of car from tower]

tan30= adjacent side/opposite side

$1/\sqrt{3}$= AB/BC

$\sqrt{3}$BC= AB

$40=\sqrt{3}AB$

$40/\sqrt{3} =AB$
