Diameter = 10.0002 inches, or 10 inches since were rounding to the nearest whole number.
Idk u think I you use division I just really want point ♀️
Ok so I uploaded the picture of how to do the promblem step by step so you know :)
Height of the flagpole = x
distance from flagpole to the mirror = 48 ft
height of Michele = 5 ft
distance from Michele to the mirror = 12 ft
Now, set the proportion.
x/48 = 5/12
48 * x/48 = 5/12 * 48
x = 240/12
x = 20
So, the height of the flagpole is 20 ft.
HOPE THIS HELPS!!!!
