document.write( "Question 984693: One angle of a triangle has a measure of 66 degrees. The measure of the third angle is 57 degrees more than half the measure of the second angle. The sum of the angle measures of a triangle is 180 degrees. What is the measure of the second angle? What is the measure of the third angle? \n" ); document.write( "
Algebra.Com's Answer #605492 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! Angle 1=66 \n" ); document.write( "Angle 2=x \n" ); document.write( "Angle 3 = (1/2)x + 57. \n" ); document.write( "; \n" ); document.write( "Therefore, 66+x+(1/2)x+57=180 \n" ); document.write( "1.5x + 123=180 \n" ); document.write( "1.5 x = 57 \n" ); document.write( "x=38 degrees, dividing both sides by 1.5 \n" ); document.write( "; \n" ); document.write( "Angle 1 is 66 \n" ); document.write( "Angle 2=38 ANSWER \n" ); document.write( "Angle 3=76 units all degrees. ANSWER \r \n" ); document.write( "\n" ); document.write( "They add to 180 degrees. \n" ); document.write( " |
