Algebra.Com's Answer #354624 by Theo(13342) You can put this solution on YOUR website! you have a right triangle. \n" ); document.write( "one angle is equal to 90 degrees. \n" ); document.write( "another angle is equal to x + 37 degrees. \n" ); document.write( "another angle is equal to x + 67 degrees. \n" ); document.write( "the sum of the angles of a triangle must be equal to 180 degrees. \n" ); document.write( "since one of the angles is equal to 90 degrees, that means that the sum of the other 2 angles must be equal to 90 degrees. \n" ); document.write( "your formula is: \n" ); document.write( "x + 37 + x + 67 = 90 \n" ); document.write( "combine like terms to get 2x + 104 = 90 \n" ); document.write( "subtract 104 from both sides of the equation to get 2x = -14 \n" ); document.write( "divide both sides of the equation by 2 to get x = -7 \n" ); document.write( "the value of x is -7. \n" ); document.write( "one angle is equal to 90 degree \n" ); document.write( "another angle is equal to 37 - 7 = 30 degrees \n" ); document.write( "another angle is equal to 67 - 7 = 60 degrees \n" ); document.write( "the sum of all the angles is 180 degrees \n" ); document.write( "that's your answer. \n" ); document.write( "x = - 7 \n" ); document.write( " \n" ); document.write( " |
