document.write( "Question 761717: In a triangle, the measure of the first angle is twice the measure of the second angle. The measure of the third angle is 68 more than the measure of the second angle. Use the face that the sum of the three measures of the three angels of a triangle is 180 degree to find the measure of each angle. a) the measure of the smallest angle. b) The measure of the second largest angle. c) the measure of the largest angle. \n" ); document.write( "
Algebra.Com's Answer #463459 by Cromlix(4381)![]() ![]() You can put this solution on YOUR website! Second angle = x \n" ); document.write( "First angle = 2x \n" ); document.write( "Third angle = x + 68 \n" ); document.write( "x + 2x + (x + 68) = 180 \n" ); document.write( " 4x + 68 = 180 \n" ); document.write( " 4x = 112 \n" ); document.write( " x = 28. \n" ); document.write( "First angle = 56 degrees \n" ); document.write( "Second angle = 28 degrees \n" ); document.write( "Third angle = 96 degrees \n" ); document.write( " Total = 180 degrees. \n" ); document.write( "Hope this helps. \n" ); document.write( ":-) \n" ); document.write( " |
