Answer:
Interior-140° Exterior-40°
Step-by-step explanation:
The sum of the interior angles of a polygon are given by 180(n-2) where n is the number of sides.
Therefore, the sum of all interior angles in a nonagon is 180(9-2) or 180×7. This equals to 1260°.
To get the individual interior angle, you use , with n defined above and s being the sum of interior angles.
Therefore, each angle is °, which can be solved to 140°.
The value of an individual exterior angle is given by 180-i, with i being the individual interior angle (this is because the 2 angles form a straight line).
In this case, 180-140=40°.
Each interior angle of a nonagon is 140°, and each exterior angle is 40°.

Answer:
$ 2533.594
Step-by-step explanation:
The saving balance is found by the equation;
where P=monthly payments, i= interest rate n=period
Given ;
P= $250 n=9months and i=6%(0.04) per year, find savings balance?
Note than n is given in months so we divide the rate by 12 i.e
0.04/12 =0.003
Substitute values in the formulae;
SV= 250 × [((1+0.003)^9 - 1)/0.003)]
