Algebra.Com's Answer #746515 by addingup(3677) You can put this solution on YOUR website! the hypotenuse is 2 miles long \n" ); document.write( "the angle the hypotenuse makes with the ground is 4 degrees \n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ \n" ); document.write( "the angle given is for the hypotenuse-adjacent. And the side we are trying to find is the opposite. So we have the hypotenuse and want to find the opposite \n" ); document.write( "Remember SOHCAHCOA. Here we have SOH (Sine Opposite Hypotenuse) so we will need to use Sine: \n" ); document.write( "sin(4) = o/2 \n" ); document.write( "0.0698 = o/2 \n" ); document.write( "0.0698(2) = o \n" ); document.write( "0.1396 = o \n" ); document.write( "So, the opposite is the vertical wall and it measures 0.1396 miles or 737 feet (0.1396 x 5280 = 737) \n" ); document.write( " \n" ); document.write( " |
