\n" ); document.write( "You must pick the correct one of these equations to use:\r
\n" ); document.write( "\n" ); document.write( "\"SINE=%28OPPOSITE%29%2F%28HYPOTENUSE%29\"
\n" ); document.write( "\"COSINE=%28ADJACENT%29%2F%28HYPOTENUSE%29\"
\n" ); document.write( "\"TANGENT=%28OPPOSITE%29%2F%28ADJACENT%29\"\r
\n" ); document.write( "\n" ); document.write( "Always look at which two sides are involved, whether given or
\n" ); document.write( "asked to find, whether they are \"OPPOSITE\", \"ADJACENT\" or \"HYPOTENUSE\". \r
\n" ); document.write( "\n" ); document.write( "Here, the given side 14 is ADJACENT to the 25° angle, and the side
\n" ); document.write( "to find x is OPPOSITE the 25° angle. Therefore, we pick the only
\n" ); document.write( "equation above that has both ADJACENT and OPPOSITE in it. So we
\n" ); document.write( "know to use the third one, for that is the only one of the three
\n" ); document.write( "that has both ADJACENT and OPPOSITE.\r
\n" ); document.write( "\n" ); document.write( "So we write
\n" ); document.write( "\"TANGENT=%28OPPOSITE%29%2F%28ADJACENT%29\"\r
\n" ); document.write( "\n" ); document.write( "\"tan%2825%29\" = \"x%2F14\"\r
\n" ); document.write( "\n" ); document.write( "Put a 1 under the left side:\r
\n" ); document.write( "\n" ); document.write( "\"%28tan%2825%29%29%2F1\" = \"x%2F14\"\r
\n" ); document.write( "\n" ); document.write( "Now cross multiply:\r
