Answer:
71 degrees
Step-by-step explanation:
Let's close the top part of the picture to make a parallelogram.
A parallelogram's four angles at each corner MUST be equal to 360 degrees.
Another property of a parallelogram is the opposite angles are congruent, meaning they're equal.
So, using these properties, we can now solve for a.

So, after one year will will have the new population of 23 000 * (100 %+2%)
(the 100 % is the old population and the 2% is the increase), that is:
23000*1.02=23460
(102 % can be represented as 1.02)
And for the next years, we have to repeat the procedure.
a more generic rule would be:
y=23000*
(x is the number of years passed)
(the 100 % is the old population and the 2% is the increase), that is:
23000*1.02=23460
(102 % can be represented as 1.02)
And for the next years, we have to repeat the procedure.
a more generic rule would be:
y=23000*
