As the regular pentagon there is 5 regular triangles.
And the area of 1 regular triangle is:
At = Side^2 × √(3)/4
But, as the pentagon has 5 triangle
Then,
Ap = 5 × Side^2 . √(3)/4
Replacing Ap = 6.9
5 × Side^2 . √(3)/4 = 6.9
Side^2 . √(3)/4 = 6.9 ÷ 5
Side^2 . √(3) = 4 × 1,38
Side^2 = 5,52 ÷ √(3)
Side^2 = 3,187
Side = √(3,187)
Side = 1,785 cm
Then,
The total perimeter will be:
P = 5 × Side
P = 5 × 1,785
P = 8,92 cm
Well, I did find this answer.
That would be vertical angles if they are angle opposite each other when 2 lines intersect.
Total = Principal * (1 + rate/n)^n*years where "n" is the number of compounding periods
Total = 9,250 * (1 + .07/52)^52*5
Total = <span>9,250 * (1.0013461538</span>)^260
<span><span>Total = 9,250 * 1.418733571
</span>
</span><span>Total = 13,123.29</span>
