Here we go !!

Since it's a regular pentagon, all it's sides are equal so let's solve for x

\hookrightarrow \: 3(x - 1)  = 5x - 6

\hookrightarrow \: 3x - 3 = 5x - 6

\hookrightarrow \:  3x - 5x =  - 6 + 3

\hookrightarrow \:  - 2x =  - 3

\hookrightarrow \: x =  \dfrac{ - 3}{ - 2}

\boxed{\boxed{x =  \dfrac{3}{2} }}

now let's find the measure of each side, i.e

\hookrightarrow \: 5x - 6

\hookrightarrow \: (5 \times  \dfrac{3}{2})  - 6

\hookrightarrow \:  \dfrac{15}{2}   - 6

\hookrightarrow \: 7.5 - 6

\mathrm{\hookrightarrow \: 1.5 \: units}

perimeter = 5 × side length ( for a regular pentagon )

\hookrightarrow \: 1.5 \times 5

\boxed{ \boxed{ \:  \:  \:  \:  \:  \:  \:  \: 7.5 \:  \:  units \:  \:  \:  \:  \:    \:  \:  }}

A 12-foot cable attached to the top of the mast of a sailboat is fastened to a point on the deck 4 feet from the base of the mas
Vilka [71]

Answer:

The height of the mast is 8√2 feet

Step-by-step explanation:

In this question, we are asked to calculate the height of the mast given the information in the question.

Please check the attachment for diagrammatic representation.

From the diagrammatic representation, we can conclude that we are asked to calculate the value of the third side of a right angled triangle, given the length of the two other sides.

Using the pythagoras’s theorem;

Square of hypotenuse = square of opposite + square of adjacent

From the diagram, we can see that the length of the cable represents the hypotenuse.

Hence;

AB^2= BC^2 + AC^2

12^2 = 4^2 + AC^2

144 = 16 + AC^2

AC^2 = 144 - 16

AC^2 = 128

AC = √128

AC = 8√2 feet

You purchase a laptop for $399.99, a carrying case for $24.99 and some cleaner for $5.00. The sales tax rate on your purchase is
Lynna [10]

Answer:

$461.15

Step-by-step explanation:

Total amount of items:

Add all the prices together

399.99+24.99+5=429.98

Sales tax:

Convert 7.25% to a decimal

7.25/100=0.0725

Multiply the total by the decimal

429.98*0.0725=31.17355

Final cost:

Add the sales tax and total amount

429.98+31.17355=461.15355

Round to the nearest cent/hundreth

$461.15

Hope this helps! :)
