Algebra.Com's Answer #593922 by rothauserc(4718)![]() ![]() You can put this solution on YOUR website! tan(45) = h1 / 100, where h1 is height above the transit \n" ); document.write( "h1 = 100 * tan(45) \n" ); document.write( "h1 = 100 \n" ); document.write( "h(height of building) = 100 + 12 = 112 \n" ); document.write( "answer is b \n" ); document.write( " \n" ); document.write( " |
