1. A seismograph detected an earthquake with an epicenter 100km from it. Another seismograph, 108km north, 36km east from the first seismograph, detect the earthquake with the same epicenter 100km from it. a. Determine the possible distance/s of the epicenter of the earthquake from the
first seismograph.

b. Assume that the first seismograph is at the origin. If the earthquake has been
traced from a fault line with an equation of x - 3y = 12, what is the exact location of the epicenter of the earthquake?
