Algebra.Com's Answer #361167 by stanbon(75887) ![]() You can put this solution on YOUR website! the terminal arm of angle ϴ passes through the point R(-15,-8) \n" ); document.write( "Draw a line segment connecting (0,0) and (-15,-8) \n" ); document.write( "That is the hypotenuse of a right triangle with sides equal \n" ); document.write( "to 15 and 8 \n" ); document.write( "------------------------------- \n" ); document.write( "determine the distance from the origin to point R \n" ); document.write( "Use Pythagoras: \n" ); document.write( "d = sqrt[15^2+8^2] = 17 \n" ); document.write( "------------------------------------- \n" ); document.write( "determine the exact value of sin ϴ to the nearest tenth of a degree \n" ); document.write( "sin(theta) = opposite/hypotenuse = -8/17 =-0.4706 \n" ); document.write( "theta = sin^-1(-8/17) = 180-28.07 = 151.9 degrees \n" ); document.write( "========================= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "--------- \n" ); document.write( " |
