Question

the shadow of a tower standing on a level ground is found to be 20m longer when the sun altitude is 45 than when it is 60 ​

Answer 1

Answer: hello here is ur answer

let ABC BE A RIGHT ANGLE TRIANGLE

right angled at b and AB = H (HEIGHT OF  TOWER)

shadow length = BC = 20 M

ALTITUDE OF SUN = 45 DEGREE

applying tan 45

h/20 = 1

h = 1 * 20

h = 20

thus the height of tower also also 20m

hope it helps!!!!!!!!!!!
