62. Height Kirsten places her surveyor's telescope on the top of

Solnce55 [7]

Answer:

21 feet

Step-by-step explanation:

Given :

Height of the tripod above the ground = 5 ft

Elevation = 8°

Distance of the tree from the tripod = 120 ft

Therefore from the figure, we can find the height of the tress as:

$\tan 8 ^\circ = \frac{BC}{AB}$

$0.1405 = \frac{BC}{120}$

∴ BC ≈ 16

Therefore, CE = BC+BE

= 16 + 5

= 21

Therefore the height of the tree is 21 feet.
