For the final exam in a scuba diving certification course, Karl navigates from one point in a lake to another. Karl begins the test $x$ meters directly beneath the boat and swims straight down toward the bottom of the lake for 8 meters. He then turns to his right and swims in a straight line parallel to the surface of the lake and swims 24 meters, at which point he swims directly from his location, in a straight line, back to the boat. If the distance that Karl swims back to the boat is 26 meters, what is the value of $x ?$
So it says this is a summary of twelve hundred responses, and so we want to see based on the table how many of those surveyed got most their medical information from either a doctor or the Internet. So here's the doctor responses in sixty three person Internet is thirteen percent. So if what if we saw his doctor or Internet, we know or means to add it. So we're going to add the percentages for doctor and Internet pretty sixty three percent plus thirteen percent. We're going to get seventy six percent. So then we're going to take that seventy six percent and find what, seventy six percent of twelve hundred?

Point seven six was going to be nine hundred and twelve. Some see is our answer
