Answer: 147 Degrees
Step-by-step explanation
The size of the final unknown interior angle in a polygon is 147 degrees.
Given that,
The other interior angles are 162°, 115°, 120°, 148° and 85°.
We assume that there is an equation (2n - 4) 90.
Here n be 7.
Based on the above information, the calculation is as follows:
= (2n - 4) 90
= ((2) (7) - 4) 90
= 10 (90)
= 900
Now the size of the unknown interior angle is
= 900-(162+125+148+105+98+115)
= 900 - 753
= 147°
Therefore we can conclude that the size of the final unknown interior angle in a polygon is 147 degrees.
The water flows 6 liters per minute in the other branch of pipe.
Step-by-step explanation:
Given,
Flow of water in main pipe = 10L/min
Flow of water in one branch = 4L/min
Flow of water in other branch = x
Flow of water in main pipe = Flow in one branch + Flow in other branch

The water flows 6 liters per minute in the other branch of pipe.
Let start off with 5/8+7/8= 1 4/8
Now it's 13+1 4/8= 14 4/8 or 14 1/2 :)
148,00 I think I don’t know if I’m right
<span>2divided 5 =</span>0.4
if 2 is over the 5 you divide the 2 by 5 to get the decimal and then you get 0.4/
