Step-by-step explanation:
Equilateral correctly describes pentagon
ΔABC ~ ΔADE
AC/AE = AB/AD
AC/(AC+15) = 8/18
18AC = 8(AC+15)
18AC = 8AC + 120
18AC - 8AC = 120
10AC = 120
AC = 120/10
AC = 12
Pi is just 3.14--- math questions will most likely ask you to round to the nearest tenth or something of the sort -
1.625 or/and 13/8 should be your answer
