The interior angles of a 7 sided figure add up to 900o That's because if you pick any vertex of an angle and draw diameters so that you create triangles, you will get 5 triangles. In general the interior angles will add up to (n - 2)*180 where n is the number of sides of a polygon.

So the simple way to do this is to equate the seven angles + x to 900

Equation

x + 125 + 126 + 158 + 120 + 139 + 121 = 900

Solve

x + 789 = 900  Subtract 789 from both sides.

x = 900 - 789

x = 111  <<<<< answer

The normal water level in the river is 0. Now it is 2 feet below normal.
Mademuasel [1]

The question can't be answered with the information given.

First of all, we don't know how fast the rain is falling ... how many inches
per hour.

But even of we knew that, that would only tell us how much water would
pile up in our yard or on our street.  You're talking about a river, and
that's a whole different ball game. 

The rain that falls right here is going to flow down the river to somewhere
else.  But the rain that falls up-river from us is going to flow down to where
we are, and the river is going to rise.  The amount it rises depends on . . .

-- how fast the rain is falling,
-- how much area it's falling on,
-- how much forest there is in that area and how many houses and
         parking lots where the ground can't soak up the water and hold it,
-- and also on how wide the river is and how fast the water can flow through it.

A realtor makes a commission of $11,400 on a $190,000 house he sells. What is his commission rate?
Reika [66]
So bassically
his commision rate is
x% times 190000=comission
so x% times 190000=11400
divide both sdies by 190000
x%=11400/190000
solve for x percent
11400/190000=114/1900=3/50
x%=3/50
percent means parts out of 100 so x%=x/100
x/100=3/50
3/50=6/100
x/100=6/100
multiply both sdies by 100
x=6

the commision rate is 6%

A round silo is 55 feet tall and has a 24 foot radius. How high would a load of 38000 cubic feet of grain fill the silo?
VARVARA [1.3K]

Find the volume of the silo.

The formula is: Volume =  PI x r^2 x h

Replace volume with the volume of grain and solve for h:

38000 = 3.14 x 24^2 x h

38000 = 3.14 x 576 x h

38000 = 1808.64 x h

Divide both sides by 1808.64

h = 38000 / 1808.64

h = 21.01

The grain would be 21.01 feet ( round to 21 feet.)
