Algebra.Com's Answer #169587 by drj(1380)![]() ![]() You can put this solution on YOUR website! One angle of a triangle is 35 degrees greater than the smallest angle and the third angle is 15 degrees less than twice the smallest angle. Find the measures of the 3 angles.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 1. The sum of the three angles for a triangle is 180 degrees.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 2. Let x be the smallest angle.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 3. Let x+35 be the second angle since it's 35 degrees greater than the smallest angle.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 4. Let 2x-15 be the third angle since it is 15 degrees less than twice the first.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 5. Then, \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 6. Solving the equation \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Subtract 20 from both sides of the equation\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 6. ANSWER: The angles of the triangle are 40, 75, and 65 degrees.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "I hope the above steps were helpful.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "For FREE Step-By-Step videos in Introduction to Algebra, please visit http://www.FreedomUniversity.TV/courses/IntroAlgebra and for Trigonometry visit http://www.FreedomUniversity.TV/courses/Trigonometry.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Good luck in your studies!\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Respectfully, \n" ); document.write( "Dr J \n" ); document.write( " \n" ); document.write( " |
