respect soively, if the height of girl is 0.8m, then the height of the lamp post is​

Answer 1

Answer:

height of the lamp post = 2.4m

Step-by-step explanation:

Let the height of the lamp post be 'x'

1.6/ 4.8 =  0.8/ x

1/3 = 0.8 / x

x = 2.4 m

Note: the triangles formed by the two will be similar by A.A similarity.

[they are standing vertically hence they are perpendicular to the ground and the adjacent angle on the ground will be equal because they are standing at a specific time under the sun, therefore the angle made by the sun and ground at the same time will be equal.]
