The exterior angles of a polygon all add to 360, if you need to find an exterior angle when given the number of sides and that all angles are equal you simply do: 360/ number of sides.
When you need to find the exterior angle when given an interior angle, you do: 180- interior angle.
Hope this helps :)
P + s = 200......p = 200 - s
20p + 15s = 3400
20(200 - s) + 15s = 3400
4000 - 20s + 15s = 3400
-20s + 15s = 3400 - 4000
-5s = - 600
s = -600/-5
s = 120 <=== there were 120 standard tickets sold
p + s = 200
p + 120 = 200
p = 200 - 120
p = 80 <=== there were 80 premium tickets sold
We can withdraw a equation to give mexico population
P = M.(1 + i)^t
So,
First of all, how many years passed? 2015 - 2000 = 15. Our time is 15, our annual rate is 1,7%, time to calc.
P = 100350000.(1 + 1,7%)^15
1,7% = 0,017
P = 100350000.(1 + 0,017)^15
P = 100350000.(1,017)^15
P = 100350000.1,2876988084901218382866596204289
P = 129220575,43198372647206629291004
Rounding
P = 129,220,575
In short, let x be the height of the Light House
2.5/36 = 1.5/X
===> X= (36 x 1.5)/2.5 = 21.6 meters
