Calculate the gradient of the meteor's flight path. calculate the acute angle between the flight path and the horizon (OX) correct to the nearest degree. A second meteor, on a parallel path, starts at C(6,2) and disappears below the horizon at D. Find the co-ordinates of D.Answer by josmiceli(9817)   (Show Source): You can put this solution on YOUR website!slope of path between (7,8) and (1,4) = (8-4) / (7-1) = 2/3 angle between path and horizon = inverse tan(2/3) = 33.7 degrees 2nd meteor path through (6,2) y = (2/3)x + b 2 = (2/3)6 + b 2 = 4 + b b = -2 y = (2/3)x - 2 at horizon point DE is (x,0), find x coordinate 0 = (2/3)x - 2 (2/3)x = 2 x = 3 at horizon point DE is (3,0)
