\huge\bold{Given:}

Length of the base = 16 km.

Length of the hypotenuse = 34 km. \huge\bold{To\:find:}

✎ The length of the missing leg ''a".

\large\mathfrak{{\pmb{\underline{\orange{Solution}}{\orange{:}}}}}

The length of the missing leg "a" is\boxed{30\:km}.

\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\orange{:}}}}}

Using Pythagoras theorem, we have

({perpendicular})^{2}  +  ({base})^{2}  =  ({hypotenuse})^{2}  \\ ⇢ {a}^{2}  +  ({16 \: km})^{2}  =  ({34 \: km})^{2}  \\ ⇢ {a}^{2}   + 256 \:  {km}^{2}  = 1156 \:  {km}^{2}  \\ ⇢ {a}^{2}  = 1156 \:  {km}^{2}  - 256 \:  {km}^{2}  \\ ⇢ {a}^{2}  = 900 \:  {km}^{2}  \\ ⇢a \:  =  \sqrt{900  \: {km}^{2} }  \\ ⇢a =  \sqrt{30 \times 30 \:  {km}^{2} }  \\ ⇢a = 30 \: km

\sf\blue{Therefore,\:the\:length\:of\:the\:missing\:leg\:"a"\:is\:30\:km.}

\huge\bold{To\:verify :}

( {30 \: km})^{2}  +  ({16 \: km})^{2}  =(  {34 \: km})^{2}  \\ ⇝900 \:  {km}^{2}  + 256 \:  {km}^{2}  = 1156 \:  {km}^{2}  \\⇝1156 \:  {km}^{2}  = 1156 \:  {km}^{2}   \\ ⇝L.H.S.=R. H. S

Hence verified. ✔

Can someone please help
chubhunter [2.5K]

Answer:


Step-by-step explanation:

She has 28056 before any deductions are taken off. As far as the IRS is concerned every penny she earns is fully accountable for the 4 categories that she has to pay into.

The problem with the question is you are not told what is wanted. Do they want the income before or after the deductions have been made or do they want the accountable sum (28056)? I don't really know. 28056 is one possible answer.

Total deductions

  • Federal Tax     3780.90
  • State Tax           770.98
  • Medicare            406.81
  • SSI                     <u>1739.47</u>
  • All Deductions  6698.16

 Income = 28056 - 6698.16 = 21357.84

I think the answer you want is 28056

One answer it is not is 4*28056 = 112224. The tax is far too low for that kind of income.

X°,Y° and Z° are three angles lying on a straight line.If X°=2y° and Z°=3y°,find he value of y
maks197457 [2]
Answer:  " y = 30° "  .
_____________________________________
<u>Note</u>:  The sum total of the measure of all angles lying on a straight
             line is 180°.

So;   x + y + z = 180 .

Given:    x =  2y ;
              z  =  3y ;
__________________
Find the value of:  " y " ;
_______________________
Since:   x + y + z = 180 ; 

Substitute:  "2y"  for  "x" ; 
          and:  "3y"  for  "z" ;
_______________________
       2y + y + 3y = 180 ;

                6y = 180 ;
______________________
  Divide EACH SIDE of the equation by "6" ; to isolate "y" on one side of the equation; and to solve for "y" ;
___________________________
       6y/ 6 = 180 / 6 ; 

             y = 30 ;
____________________________
Let us check our work;
____________________________
     2y + y + 3y = 180 ;

Substitute our solved value:  "30" ; for "y" ; in the equation; to see if the equation holds true:
____________________________
  2(30)  +  30  +  3(30)  =?  180 ?
____________________________
   60  +  30  +  90  = ?  180 ?
____________________________
             90  +  90  = ?  180 ?  Yes!
____________________________
