The sum of the inner angles of a polygon with n sides is 180(n-2)

Since your polygon has 6 sides, the sum of its inner angles has to be

180(6-2) = 180 \cdot 4 = 720

On the other hand, the sum of its inner angles is

75+132+113+108+160+x = 588+x

And it has to be 720, so we have

588+x=720 \iff x = 720-588 = 132

A machine pumps 2.1 gallons of water every 1.6 minutes. How many gallons is pumped per minutes?
maks197457 [2]

Answer:  1.3125 gallons

Step-by-step explanation: The machine pumps 2.1 gallons of water every 1.6 minutes. 1.6 minutes is 1.6x more than 1 minute. So, we have to divide 1.6 by 1.6. Next, we have to divide 2.1 by 1.6. We can make this a bit easier by multiplying both of them by 10 to get 21/16 which is 1.3125.
