Answer 2

Answer:

Explanation:

The angles are same because sun rays will strike parallely to the pole and the tree.

so, by pythogoras theorem hypotenuse created by shadow and pole

= root of 14^2+ 10^2

= root of 196+100

= root 296

= 17.2=172/10 = hypotenuse

cos theta = 10 divided by 172/10

= 10 x 10/172

= 100/172

= 0.58 = ~3/5

the triad is 3,4and 5.

hence angle = 37 degrees.

tree height is base times =

7 times tan 37= 7x 3/4=21/4=5.25m

unless it says round to nearest real number ans: is d

but if you round it ans: is c.

hope my ans: helped you

pls mark me as brainliest.

and pls mark me as having the best answer!!!

thank you
