So the answer is A.......
Answer:



Step-by-step explanation:
Given
The attached figure


Solving (a): EF
Since m is a perpendicular bisector, then <EGF and <EGH are right-angled.
So, EF will be calculated using Pythagoras theorem which states:




Take the positive square roots of both sides


Solving (b): GH
Since m is a perpendicular bisector, then GH = FG



Solving (c): EH
Since m is a perpendicular bisector, then EH = EF



A. $0.02 per golf tee
To check this answer;
0.02 * 150 golf tees = $3
Let me know if this helps :)
I first converted 23 ft to inches by multiplying by 12
23 ft= 276 in
I then added the half inch so it became 276.5 inches
converting back to ft, by dividing by 12
276.5 in= 23.04 ft
