Answer:
The percent for 3 out of 12 is 25%

3/12 = 0.25 which means 25% because 0.25 is 25% of 1.
Using the same percentage for 100 total games, you just multiply 100 by 0.25, the decimal version of the percentage.
Given that triangle ABC is right angle triangle. CD is altitude such that AD=BC
ABC is a right angle triangle so apply Pythogorean theorem

(Given that AD = BC)
(Given that AB=3)
...(i)
ADC is a right angle triangle so apply Pythogorean theorem



...(ii)
Plug value (ii) into (i)





Hence final answer is
