DETERMINE ACUTE ANGLE Between Pairs Of Lines (1)

In this video, I share with you steps for using concepts of vector and parametric equations of lines to find the acute angle between the lines. For each pair of lines, determine the size of the acute angle, to the nearest degree, that is created by the intersection of the lines. @24x7MathTutor #equationofline #equationofaline #equationofstraightline #vectoralgebra #vectors #vector #maths #math #mathematics #anilkumarmath #vectoralgebra #calculusandvectors #vectortipsandtricks #algebra #algebraicequations #algebraicexpression #khanacademy #khanacademyeducation #cartesian #cartesianequation #directionvector #vectorequation #dotproduct
