3. Suppose AABC SA EFG, and EG = 7x-11, AB = 5x -9, GF = 3x -1, and AC = 2x + 4. Find the value of x and the lengths of the sides of A EFG.
Part I: Sketch the triangles below.(3 points)
Part II: Use measures for AC and EG to find the value of x. Show your work.
(2 points)
Part III: Find the lengths of the sides of A EFG. Show your work.

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function.a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.
