Using the Pythagorean theorem, we can calculate the apothem of the pentagon.
We have then:
Then, the area of the pentagon is given by:
Where,
L: side of the pentagon
a: apotema
Substituting values:
Rounding the nearest whole we have:
Answer:
the approximate area of the regular pentagon is:
The final result is:
no solutionSince we canceled 8x out on each side of the problem, we got 16 = -6 which is false.
Step-by-step explanation:
Step 1: Factor both the numerator and the denominator.
Step 2: Write as one fraction.
Step 3: Simplify the rational expression.
Step 4: Multiply any remaining factors in the numerator and/or denominator.
Step 1: Factor both the numerator and the denominator.
Step 2: Write as one fraction
