Phillip : In 1 hour he can paint 1/6 of the room.
Wade : In 1 hour he can paint 1/9 of the room.
(1/6)x + (1/9)x = 1 ' their rates together must total 100%
(15/54)x = 1 ' together they paint (15/54)% in 1 hour
x = 54/15 or 3.6 hours

So the scale of the lacking facet is the fringe of the triangle minus the sum of the two given aspects. The sum of the two given aspects is (5x_2 + 3x + 5) + (3x_2 + 4) = 8x_2 + 3x + 9 Then the scale of the lacking facet is (10x_2 + 8x + 5) - (8x_2 + 3x + 9 ) = 2x_2 + 5x - 4
