The angles of a pentagon are in ratio

ivanzaharov [21]

Answer:

216°

Step-by-step explanation:

The ratio of the sum of smallest and largest to the total of all angles is ...

(9 +15)/(9 +10 +12 +14 +15) = 24/60 = 0.4

The total of all angles in an n-gon is 180°(n -2), so the total of all angles in a pentagon is ...

180°(5 -2) = 540°

Then the sum of smallest and largest angles is ...

0.4(540°) = 216°

Mixed number equations that equal 10.<br> Please hurry.

Vladimir79 [104]

Answer:

Mixed number equation equals to 10= $9\frac{9}{9}$

Step-by-step explanation:

Here we have to find mixed number equation that equal 10,

Let, x=10 ------------(equation 1)

Now multiplying both side of equation 1 by 10 we get,

$x\times 10=10\times 10$

$10x=100$ ------------------(equation 2)

Now by subtracting equation 1 from equation 2 we get,

$10x-x=100-10$

$9x=90$

$\therefore\ x=\frac{90}{9}$ ------------------(equation 3)

Equation 3 can be written as,

$x=9\frac{9}{9}$

Since, $9\frac{9}{9}$

$= \frac{(9\times 9)+9}{9}$

$=\frac{81+9}{9}$

$=\frac{90}{9}$ [/tex]

$\therefore 9\frac{9}{9}=\frac{90}{9}$

Therefore mixed number equation that equals 10= $9\frac{9}{9}$
