)
On the graph, you would put an open dot on -5 and an arrow continuing down it
They are complementary because if you were to put them on top of one another they'd line up. (same degree measurement)
Sin = opposite/hyp
Sin A = 10/26 = 5/13
Sin b = 24/26 = 12/13
The answer is option A
Hope this helps
List the factors:
21: 1, 3, 7, 21
40: 1, 2, 4, 5, 8, 10, 20, 40
They only have 1 in common.
So 1 is the greatest common factor.
