Which statement justifies why angle abf measures 130 degrees? given: angles abd and dbc are complementary

A linear pair is two adjacent , supplementary angles

Step-by-step explanation:

Angles are supplementary when they add up to 180°

In the question,

∠ABD and ∠ABF are supplementary angles that add up to 180°

To get ∠ABF = 180°-50°=130° supplementary angles add up to 180°.This is to say angles on a straight line add upto 180°.The linear pair adjucent to one another are ∠ABD and ∠ABF
