In ∆WXY, if ∠X ≅ ∠Y, WX = 9x – 11, XY = 4x + 1, and WY = 7x – 3, find x and the measure of each side.

Richter defined the magnitude of an earthquake to be m = log i/s , where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. the magnitude of a standard earthquake is m = log s/s =
