To solve this you need to know Pythagorean theorem.
First, EG is 24, so the halfway points are 12. Knowing Pythagorean triples, you can use 5,12,13 and 12,16,20.
DF = 5+16
DF = 21
If you don't know Pythagorean triples, I have worked it out on the image attached.
Try YouTube there should be videos on how to do it .
This is the work and the answer is 4/23 or (in decimal form) 0.17391304
Answer: the anwser is A
Step-by-step explanation:
I used a calculator lol
To divide fractions be multiply by the resiprical
4 6 24
