How do I do number 16?
PolarNik [594]

Answer:  x = 121 degrees

Step-by-step explanation:

(n-2) x 180

(6-2) x 180

4 x 180=720

599 +x = 720

599 - 599 = x  +x = 720 - 599 = 121

and then add up all the degrees

88 + 105 + 142 + 140 + 124 + 121 = 720

1.06(12.95+x)=31.27 solve for x
OverLord2011 [107]

Answer:

<h2>x = 16.55</h2>

Step-by-step explanation:

1.06(12.95 + x) = 31.27

<u>Multiply the terms in the bracket</u>

That's

13.727 + 1.06x = 31.27

<u>Subtract 13.727 from both sides</u>

That's

13.727 - 13.727 + 1.06x = 31.27 - 13.727

1.06x = 17.543

<u>Divide both sides by 1.06</u>

That's

\frac{1.06x}{1.06}  =  \frac{17.543}{1.06}  \\ x =  \frac{17.543}{1.06}

We have the final answer as

<h3>x = 16.55</h3>

Hope this helps you
