The height of the triangle is 48/b or 48 over b. That's all I can tell you with the information given.
Answer:
2/7
Step-by-step explanation:

Answer: Technically, it would be 9/3, but you can simplify that to 3.
5 = what percent of 23
5 = x% of 23
5 = (x/100)*23
5 = 23x/100
5*100 = 23x
23x = 5*100
x = 5*100/23
x = 21.739
5 is ≈ 21.739% of 23
