The formula for solving the area of a regular decagon is shown below:
A=(5/2)a²√(5+2√5)
where "a" refers to the measurement of the side on which in this problem, it is equal to 9.3 units
We can proceed in solving for the area and the solution is shown below:
A=(5/2)*(9.3)²√(5+2√5)
A=665.47 square units
The answer is 665.47 square units.
3. adjacent, x=49

The answer to you question is c
First we have to find a common denominator
8×3=21
7/8×3=21/24
2/3×8=16/24
21-16=5
answer is 5/24
The first number before the decimal point is the ones place.
48.26
ones = 8
The second number after the decimal point is the hundredths place:
48.26
hundredth: 6
