Answer: 2748.5 feet

Step-by-step explanation:

Given that the

Height h = 120 feet.

angle of depression = 2.5 degrees

The angle of depression is equal to the angle of elevation.

The base of the observation deck will be achieved by using trigonometry ratio.

Tan Ø = opposite/ adjacent

Opposite = height = 120 feet

Adjacent = base = ?

Substitutes the given parameters into the trigonometry ratio.

Tan 2.5 = 120 / adjacent

Adjacent = 120 / tan 2.5

Adjacent = 2748.452

Therefore, the base of the observation deck is 2748.5 feet

**I WILL GIVE BRAINLIEST TO THE PERSON WHO CAN HELP ME/AND 40 POINTS**
Mama L [17]

Tank calculations :

Volume = 1/4(4/3 * pi * r^3)

r= 70 feet.

Volume = 1/4(4/3 * 3.14 * 70^3)

Calculating the values:

Volume = 359,000.67 ft.cubed

No we divide the actual radius by 6 to get the volume of scale model.

Hence,

6^3 = 216 times smaller.
