Answer:
Step-by-step explanation:
a(1) = -7 (given)
a(2) = a(1) + 4 = -7 + 4 = -3
a(3) = a(2) + 4 = -3 + 4 = 1
a(4) = a(3) + 4 = 1 + 4 = 5
and so on.
Hey! Sorry for the 6 day late response. The answer is:
25%
Since all the inside angles are 60, in order to add up to 180, the outside angles need to be 120.
600 = 360 + 240
In unit circle, (x,y) = (cos(240), sin(240) ) = (-sqrt(3) / 2, -1/2)
If you add them all you get 50x12y13
