Thepotemich [5.8K]

Answer:

Step-by-step explanation:

Let width = w units

Length = 4w - 3

Cost for lining corners of wall = $ 18.50

Perimeter of the wall = 18.50/0.25 =  74 ft

2*(length  +width ) = 74

2*(4w - 3 + w) =74

2*(5w - 3) =74

10w - 6 = 74   {Add 6 to both sides}

10w - 6 + 6 = 74 + 6

10w = 80

Divide both sides by 10

10w/10 = 80/10

w =  8 ft

Length = 4w - 3 = 4*8 - 3 = 32 - 3

Length = 29 ft

Area of the wall = length * width

                           = 29 * 8

                           =  232 square ft

Cost of painting the wall per square feet = 20 cents = 0.20

Cost of painting 232 square feet = 232 * 0.20

                                                             = $ 46.40

The angles measures x and 4x are complementary angles. Which is the value of x?
Hitman42 [59]

<u>Answer:</u>

The angles measures x and 4x are complementary angles. The value of x is 36 degrees

<u>Solution:</u>

Given, two angles are x and 4x

We have to find the value of above given x  

We are also given that, given two angles are complementary angles for each other

So, we know that, <em>sum of any two complementary angles will always be equal to 180 degrees </em> 

Then, in the problem given,

x+4 x=180 \rightarrow 5 x=180 \rightarrow x=\frac{180}{5} \rightarrow x=36

Hence the angles measures x and 4x are complementary angles. The value of x is 36 degrees
