Algebra.Com's Answer #769731 by greenestamps(13200)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "With angle AOT 60 degrees and the radius OT=8, we can conclude that AO=16 and AT=8*sqrt(3). \n" ); document.write( "Then in right triangle XOT we have legs XT=8*sqrt(3)-m and OT=8, and hypotenuse XO=8+m. So \n" ); document.write( " \n" ); document.write( "Solving that equation, the m^2 terms on the two sides cancel, leaving a linear equation in m, making it possible to find an exact value for m (in radical form). \n" ); document.write( " \n" ); document.write( " |
