It is equal to the acute angle determined by the normal vectors of the planes. If θ is the angle between two intersecting lines defined by y 1 = m 1 x 1 +c 1 and y 2 = m 2 x 2 +c 2, then, the angle θ is given by. y = 2x(0.8)2 Calculate the angle between the planes π 1: x +2y -2z = 5 and π 2: 6x -3y +2z = 8 . First is r = (3i+2j)+t (-i+2j+k) and second is r = () + t (i+3j-k) Hence first is // (-i+2j+k) and second // (i+3j-k) So the angle between them is the same as the angle between these 2 vectors. This is called as the right angle. Homework Statement This is a problem involving parametric equations. Intersecting lines are lines that cross each other. Detailed expanation is provided for each operation. m = $$\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$$ The angle between the two lines can be found by calculating the slope of each line and then using them in the formula to determine the angle between two lines when the slope of each line is known from the equation.
