Calculate the area of the regular pentagon below:
a regular pentagon with side length of 17.6 inches and dotted line from center to middle of side of 12.1 inches.
106.48 square inches
366.025 square inches
451.78 square inches
532.4 square inches

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

probably .5

i can on others if necessary.
