Algebra.Com's Answer #375393 by ad_alta(240) You can put this solution on YOUR website! We can think of a regular pentagon as being composed of 10 right triangles with base 10/2=5. Next, determine the length of the apothem. The area is about 172.05 cm^2. We can also use the formula (5s^2/4)tan(54) for side 's,' which gives the same answer. \n" ); document.write( " |
