x 1 = 3 * cos 120° = - 3 cos 60° = - 3/2 = - 1.5 y 1 = 3 * sin 120° = 3 sin 60° = 3√3 / 2 = 2.598 x 2 = 0.5 * cos 49° = 0.328 y 2 = 0.5 * sin 49° = 0.37735479 -------------------------------------------- d = [( x 2 - x 1 )² + ( y 2 - y 1 )²]^(1/2) d = [ ( 0.328 + 1.5 )² + ( 0.37735479 - 2.598) ] ^(1/2) d = ( 3.341584 +4.931265 )^(1/2) Answer: The distance is : d = 2.876256
