Which statement justifies why ∠dbc measures 40°?

given: angles abd and dbc are complementary

point b is on line ae between points a and e, point b is on line fd between points f and d, ray bc intersects with line ae at point b, line fd intersects with line ae at point b, the measure of angle abd is 50 degrees, and it is given that angles abd and dbc are complementary.

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
