I know the hypotenuse is 5 as it is the longest measurement. I tried putting the other numbers in to get the sine SinA b/5 SinA 4/5 =.0139 but the angle of this is not the right answer. I am having trouble understanding how to use sin, cos, and tan to find answers regarding angles and sides. \n" ); document.write( "--- \n" ); document.write( "Draw the figure. \n" ); document.write( "Let the hypotenuse be 5. \n" ); document.write( "Let the angle opposite 4 be A. \n" ); document.write( "Then sin-1(4/5) = 53.13 degrees or 0.9273 radians \n" ); document.write( "---- \n" ); document.write( "The other acute angle is sin^-1(3/5) = 36.87 degrees or 0.6435 radians \n" ); document.write( "----- \n" ); document.write( "Notice that the angles are complimentary. \n" ); document.write( "=============== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
