Step-by-step explanation:

tan \theta =  \frac{49}{10}  = 4.9 \\  \\  \therefore \:  \theta =  {tan}^{ - 1} 4.9 \\  \\ \therefore \:  \theta =  {tan}^{ - 1} (tan \: 78.465379346 \degree) \\  \\  \huge \red{ \boxed{\therefore \:  \theta =  78.5 \degree}} \\

Hence, angle of elevation of sun is 78.5°.

Answer:

Below.

Step-by-step explanation:

To find the volume of the silo find the volum of the hemisphere with radius of 15 feet and add the volume of the cylinder with a radius of 15 feet and a height of (100 - 15) = 85 feet.

The total volume = 1/2 * 4/3 π (15)^3  + π (15)^2 * 85

= 67151.5 ft^3.

Answer:

Step-by-step explanation:

Draw a horizontal line at the end of the 8 meter horizontal line.

Find the area of the horizontal rectangle

L = 8 + 3

W = 2

Area = L*w

Area = 11*2

area = 22 m^2

Now do the vertical rectangle

L = 8

w = 3

Area = L*w

Area = 8 * 3

Area = 24 m^2

Total Area = 24 + 22 = 46 m^2

Which side lengths form a right triangle.
belka [17]
Answer: B

Explanation:

Use Pythagorean’s theorem to find it out:

A^2 + B^2 = C^2

8^2 + 15^2 = 17^2

64 + 225 = 289

289 = 289

So these side lengths create a right triangle
