The answer should be 4.3 (the line is ontop of the 3)
The line is on the 3
We know that
The sum of exterior angles of any polygon is 360 degrees.
Each exterior angle of a regular polygon = 360/n
where n is the number of sides.
<span>So
n = 360/20 = 18
</span>
the answer is the option
<span>b.18 </span>
BD is congruent to BD by the reflexive property
AD is congruent to DC because they are both created by the midpoint D
so with all the together you can say the triangle are similar by SSS
two years at 3% = .03*2 = .06
so
.06 times original deposit = 72
so 72/.06
which is
1200
