Use the diagram to find the height of statue.round to the nearest tenth

jeyben [28]

Answer:

7.3 ft

Step-by-step explanation:

The information given represents a right angle triangle with the following:

reference angle = 52°

Adjacent side length = 5.7 ft.

Opposite side length = height of the statue = h

Applying the trigonometric ratio formula, we would have:

$tan(52) = \frac{h}{5.7}$

Multiply both sides by 5.7

$tan(52) \times 5.7 = \frac{h}{5.7} \times 5.7$

$tan(52) \times 5.7 = h$

$h = 7.3 ft$ (nearest tenth)

Answer:

$90\pi$

Step-by-step explanation:

The first step is to find the slant height of the cone. Using the pythagorean theorem, you can find that $\sqrt{12^2+5^2}=13$ cm. Plugging this into the equation, you get $\pi \cdot 5 \cdot 13=90\pi$ . Hope this helps!
