Answer:
1170
Step-by-step explanation:
<u><em>Total Population</em></u> = 900
<u><em>Annual rate of increase </em></u>= 30 % of 900
=>
=> 30 * 9
=> 270
<u><em>Population next Year </em></u>= 900+270
=> 1170
164
Remember, everytriangle is 180 all together. So add what you see and subtract it from 180.
9+7= 16
180-16= 164
