Need help with algebra 2!

Answer:

x=38.56

Step-by-step explanation:

First, we'll solve for the missing angle.

The interior angles of a triangle add up to 180, so let's make an equation.

35+90+x=180 \\ \\ 125+x=180 \\ \\ x=55

Now we can use the law of sines.

\frac{a}{sin(A)}=\frac{b}{sin(B)}

Where the lowercases are the side lengths and the uppercases are the angle measures.

Plug in the values we know.

\frac{27}{sin(35)}=\frac{x}{sin(55)}

Solve using a calculator.

x=38.55999618 \\ \\ x=38.56

Can someone please help with this math question:)
Bingel [31]

<u>Solution</u><u>:</u>

The rationalisation factor for \frac{1}{ a -  \sqrt{b}  } is a + \sqrt{b}

So, let us apply it here.

\frac{1}{5 -  \sqrt{2} }

The rationalising factor for 5 - √2 is 5 + √2.

Therefore, multiplying and dividing by 5 + √2, we have

=  \frac{1}{5 -  \sqrt{2} }  \times  \frac{5 +  \sqrt{2} }{5 +  \sqrt{2} }  \\  =  \frac{5 +  \sqrt{2} }{(5 -  \sqrt{2})(5 +  \sqrt{2} ) }  \\  =  \frac{5 +  \sqrt{2} }{ {(5)}^{2} - ( \sqrt{2})^{2}   }  \\  =  \frac{5 +  \sqrt{2} }{25 -  2}  \\  =  \frac{5 +  \sqrt{2} }{23}

<u>Answer:</u>

<u>\frac{5 +  \sqrt{2} }{23}</u>

Hope you could understand.

If you have any query, feel free to ask.

Answer:

n = -2

Step-by-step explanation:

add 7 to both sides

1+8n = -15

subtract 1 from both sides

8n = -16

divide both sides by 8

n = -2

SCORPION-xisa [38]

Answer:

Markup= 1.81

Sale price =9.06

Step-by-step explanation:

The markup is the original prices times the markup rate

markup = 7.25 * 25%

            = 7.25 * .25

             =1.8125

We round this to the nearest cent

           =1.81

The new sale price will be the original price + the markup

7.25+1.81

9.06
