Question

when the sun is at an elevation of 40° the shadow
of a flag post is 15 m
a) Find the height of the flag post?
b) What would be the length of the shadow, when
the sun is at an elevation of 45°
[tan40=0.84,sin 40=0.64]

Answer 1

Answer:

Hello...

(a) Height of the flag post

tan 40 =x/15

0.84= x/15

x = 0.84 ×15 =12.6....

(b)Tan 45 = L/15

1 = L/15

L = 15
