is there someone who can help me ? i will appreciate!

Find the direction cosines and direction angles of the vector. (Give the direction angles correct to the nearest degree.) (5, 1, 5) cos((1} = E E Find the scalar and vector projections of b onto a. a = (3, 4), b = (6, 7) scalar projection of b onto a vector projection of b onto a The distance from a point P1(x1, yl) to the line ax + by + c = 0 is |ax1 + byl + Cl \\/a2 + b2 Use this formula to find the distance from the point (3, 5) to the line 3x 4y + 4 = 0. \f\f
