document.write( "Question 1054527: How do you use angles to find the missing lengths of a triangle?
\n" ); document.write( "I know that there angles of a triangle are 20,70,90 and that the length of the leg adjacent to the 70 angle that isn't a hypotenuse is 30. How do I find the length of the other two lengths? I tried using the law of sines but maybe i did something wrong because i ended up with 29.377336 and 25.43057.

By definition,
\n" ); document.write( " $\"sin%2820%29=30%2FH\"$
\n" ); document.write( " $\"H=30%2Fsin%2820%29\"$
\n" ); document.write( " $\"H=87.7\"$
\n" ); document.write( "So then the other leg is,
\n" ); document.write( " $\"Hcos%2820%29=87.7%280.9397%29=82.4\"$
\n" ); document.write( " \n" ); document.write( "
