Algebra.Com's Answer #41824 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! Consider triangle ABC. It is given that AB = AC, AB = 4x + 2y, BC = 5x, and AC= 10y. is the triangle equilateral? Justify answer \n" ); document.write( ": \n" ); document.write( "It may help to draw a triangle and label the sides as given: \n" ); document.write( ": \n" ); document.write( "Since AB = AC we can say: \n" ); document.write( ": \n" ); document.write( "4x + 2y = 10y \n" ); document.write( "4x = 10y - 2y \n" ); document.write( "4x = 8y \n" ); document.write( "x = (8/4)y \n" ); document.write( "x = 2y \n" ); document.write( ": \n" ); document.write( "If x = 2y and the third side, BC, is given as 5x, we can say: \n" ); document.write( "5x = 5(2y) = 10y which is given as side AC, so it is, in fact, equilateral. \n" ); document.write( ": \n" ); document.write( ": \n" ); document.write( "What is the smallest number that the sum of the two largest angles in a scalene triangle can be if all the angle measures are whole numbers? \n" ); document.write( ": \n" ); document.write( "I guess that means that the 2 equal angles are both greater than the 3rd angle. \n" ); document.write( "It would have to be close to being equilateral triangle (all angles 60 degrees) \n" ); document.write( "I'm going to say angles of 61, 61, 58, smallest sum would be 122 degrees. \n" ); document.write( ": \n" ); document.write( "Let me know if I am wrong about this. \n" ); document.write( " |
