To calculate the cost of painting his silo, a farmer must find its height. The farmer uses a cardboard square to line up the top

musickatia [10]

Answer:

Height of the silo = 18 feet.

Step-by-step explanation:

From the figure attached BC is the length of the silo and the height of the farmer is 5 ft.

Farmer is standing at 8 ft distance from the silo.

From triangle AEC,

tan(∠CAE) = CE/AE=5/8

m(∠CAE) = tan-1 (5/8)

= 32°

m∠BAE = 90° - 32° = 58°

From the triangle ABE,

tan58° = BE/AE

BE = 8tan58°

BE = 12.8 ft

Total height of the silo = BE + EC

= 12.8 + 5

= 17.8

≈ 18 ft

Therefore, the total height of the silo is 18 ft.

Hello!

I've altered the diagram and attached it below. I've added a circle; circles measure 360°. Segment CD is half the measure of the circle, thus it measures 180°. That means that if you add all the angle measures up, they have to equal 180°. Let's make an equation.

180 = (4x + 8) + 34 + (76 - x)

Now we can solve algebraically for x.

180 = 4x + 8 + 34 + 76 - x
180 = 3x + 118
62 = 3x
20.67 ≈ x

Answer:
x ≈ 20.67
