It forms a Triangle, in which base is shadow, and height of the tree is perpendicular.

So, Tan Ф = P / B
Tan 28 = P /18
0.53 * 18 = P    [ Tan 28 = 0.53 ]
P = 9.6

In short, Your Answer would be Option D

Hope this helps!

A balloon is rising vertically at the rate of 12 feet per second; at the same time, it is being blown horizontally by a wind of
Nuetrik [128]

Answer:

Angle is 33.82°

Step-by-step explanation:

It is given that, from the figure below,

Vertical distance = 12 feet

Horizontal distance = 18 feet.

Using the trigonometric rule for the right triangles, we have,

\tan x=\frac{perpendicular}{base}

i.e. \tan x=\frac{12}{18}

i.e. \tan x=0.67

i.e. x=\arctan 0.67

i.e. x= 33.82°

Thus, the angle made by the path with the horizontal is 33.82°.
