Would you please help me with this question..
\n" ); document.write( "In triangle ABC, AC = 18, BC =10, and cosC = 1/2. Find the area of triangle ABC to the nearest tenth of a square unit.
\n" ); document.write( "----------------
\n" ); document.write( "Assuming the triangle is a right triangle, since cos(C) = 1/2,
\n" ); document.write( "sin(C) = [sqrt(3)]/2
\n" ); document.write( "------------------------------
\n" ); document.write( "Formula:
\n" ); document.write( "Area = (1/2)ab*sin(C)
\n" ); document.write( "Area = (1/2)*10*18
\n" ); document.write( "= 5*9*sqrt(3)
\n" ); document.write( "= 77.94 sq. units
\n" ); document.write( "===================================
