Question

in the figure ab || cd ,abo = 50° and CDO = 40° measure bod​

Answer 1

Answer:

Construction:extend BO to BE on the line CD

angle AOB = angle OED (alternate interior angles)

45+50+angle DOE=180 degrees(angle sum propety of triangle)

therefore angleDOE=85 degrees

angle DOE+angle BOD=180 degrees (linear pair)

therefore angleBOD=95 degrees

Hope it helped you
