Laboratory test shows that the lives of light bulbs are normally distributed with a mean of 750 hours in a standard deviation of 75 hours. Find the probability that a randomly selected light bulb last between 600 and 750 hours

To prove that def ~ gfh by the sss similarity theorem using the information provided in the diagram, it would be enough additional information to know that
