Step-by-step explanation:
Because to make sure on the graph is counterclockwise for the vertex for the starting point.
Answer:
D.supplementary angles
Step-by-step explanation:
81+99=180
the Highest common factor of 130,260,390 = 130
130 = 2⋅5⋅13
260 = 2⋅2⋅5⋅13
390 = 2⋅3⋅5⋅13
Common multipliers (130; 260; 390): 2, 5, 13
Now to find the highest Common factor you need to multiply the common factors
Answer: (130 ; 260 ; 390) = 2 ∙ 5 ∙ 13 = 130
