To the nearest degree, what is the angle of elevation of the sun? Also, how do I know which angle the elevation of the sun is? Is it the bottom or the top angle? \n" ); document.write( "----------- \n" ); document.write( "Draw the picture: \n" ); document.write( "You have a right triangle with: \n" ); document.write( "height = 15 \n" ); document.write( "base = 8 \n" ); document.write( "--- \n" ); document.write( "Angle opposite the height is the angle of elevation. \n" ); document.write( "Call that angle \"x\": \n" ); document.write( "----- \n" ); document.write( "Equation: \n" ); document.write( "tan(x) = 15/8 \n" ); document.write( "x = tan^-1[15/8] = 61.93 degrees \n" ); document.write( "================================ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
