Algebra.Com's Answer #168075 by drj(1380)![]() ![]() You can put this solution on YOUR website! Recall that the sum of the measures of the angles of a triangle is 180 degrees. In the triangle below, angle c has the same measure as angle b, and a measures 42 degrees less than angle b. Find the measure of each angle.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 1. Given c=b \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 2. a=b-42 since angle a measures 42 less than angle b.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 3. Then, b-42+b+b=180 since c=b and the three angles add to 180 degrees.\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( "Step 4. Check if the angles equal to 180...74+74+32=180 which it does.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 6. ANSWER: Angle a is 32 degrees and angles b and c is each 74 degrees.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "I hope the above steps and explanation 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( "And good luck in your studies!\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Respectfully, \n" ); document.write( "Dr J\r \n" ); document.write( "\n" ); document.write( "http://www.FreedomUniversity.TV\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
