Answer: From the 60° angle, the flagpole is the opposite side and the shadow is the adjacent side of the triangle.

tangent 60° = opposite/adjacent  

so

tan 60°  = 20/x

multiply both sides by x and you have

x · tan60° = 20

divide both sides by tan 60° and you have

x = 20/tan60°

x = 11.5 ft.

if this is wrong sorry don’t be mad but if it’s right then hope this helps

Find the total surface area of these solids
12345 [234]
<h2>Step-by-step explanation:</h2><h3>We firstly find the surface area of only one face of the cube:</h3><h3>Sa=a²</h3><h3>Sa=1.2²cm</h3><h3>Sa=1.44cm²</h3>

<h2>Since the cube has 6 faces we multiply the surface area of one face(144cm²) with 6</h2>

Area(cube)=1.44cm²*6

=8.64cm²

<h2>Same thing with the prism but we have to find the area of one of his triangle face and rectangle face</h2>

S(triangle)=5mm*4mm*1/2

=10mm²

S(rectangle)=7mm*5mm=35mm²

<h2>The prism has 2 triangle faces and three rectangle faces so we multiply the area by those numbers and then we add those together to get the final area</h2>

S=10mm²*2+35mm²*3

S=20+105

S=125mm²

TeeVee Electronics, Inc., makes console and wide-
Tom [10]

Answer:

First we need to put all the given information in a table, that way we'll express it better into inequalities.

                                     Cost      Production Max.

Console screen (x)      $600              450

Wide-screen (y)           $900              200

                                 $360,000

We have:

600x+900y \leq 360,000

Because they can't spend more than $360,000 in production.

x\leq 450\\y\leq 200

Because the number of television is restricted.

The profit function is

P(x,y)=125x+200y (this is the function we need to maximize).

First, we need to draw each inequality. The image attached shows the region of solution, which has vertices (0,200), (300,200), (450, 100) and (450,0).

Now, we test each point in the profit function to see which one gives the highest profit.

For (300,200):

P(300,200)=125(300)+200(200)=37,500+40,000=77,500

300 console screen and 200 wide screen give a profit of $77,500.

For (450,100):

P(450,100)=125(450)+200(100)=56,250+20,000=76,250

450 console screen and 100 wide screen give a profit of $76,250.

<h3>Therefore, to reach the maximum profits, TeeVee Electronic, Inc., must produce 300 console screen televisions and 200 wide-screen televisions to profit $77,500,</h3>
