If the measure of one angle is twice the measure of a second angle, and the measure of a third angle is 40 deg less than the second, find the measure of all three angles of the triangle. \n" ); document.write( "
Algebra.Com's Answer #189926 by Greenfinch(383)![]() ![]() You can put this solution on YOUR website! Let first angle be 2y, then second angle is y and the third is y - 40. \n" ); document.write( "Sum is y + 2y + y - 40 = 180 \n" ); document.write( "4y = 220 \n" ); document.write( "y = 55 \n" ); document.write( "So angles are 110, 55, 15 \n" ); document.write( " |
