A 7m long flag staff is fixed on the top of a tower standing on the horizontal plane. From a point on the ground, the angles of elevation of the top and bottom of the flag staff are 60° and 45° respectively. Find the height of the tower correct to one place of decimal.(Use √3 =1.73)

Answer 1

Answer:

*•.¸♡ hєч ♡¸.•*

Step-by-step explanation:

(i) x/y = tan 45° = 1

⇒ x = y

( ii ) x + 7 / x → Tan60° = √3

⇒ 7 = ( √3 - 1 )x

x = 7 (√3 + 1 ) / 2

⇒ 7 ( 2.73 ) / 2

⇒ 9.6m
