Algebra.Com's Answer #658022 by solver91311(24713)![]() ![]() You can put this solution on YOUR website! \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Since the actual size of the rectangle is arbitrary, we can use the fact that the tangent of x is 3/4 to assign the value 4 to the measure of the side of the rectangle that is adjacent to angle x, and the value 3 to the measure of the side opposite angle x. The other long side of the rectangle must also be 4, and since 4 is 2/3 of 6, assign 2/3 (2/3 times 1) to the segment that is opposite angle y.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Then, relatively speaking, the area of the entire rectangle is 12 square units, the area of the triangle containing angle x is 6 square units, and the area of the triangle containing angle y is 4/3 square units. The sum of the areas of the two triangles is then 22/3 and 22/3 divided by 12 is 11/18.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Then the shaded area is 1 minus 11/18. 7/18\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "John \n" ); document.write( " \n" ); document.write( "My calculator said it, I believe it, that settles it \n" ); document.write( " ![]() \n" ); document.write( " |
