The figure is right triangle with base =segment AB = 3 and height = segment AC = 2.
The angle B has tangent, tan (B) = 2 / 3
The angle C, has tangent, tan (C) = 3 / 2
Then, the answer is option C, tan C
Its equally distant from the endpoints of the segment to find the center of the following rotation
The first figure has 3 line segments.
the second figure has 3+3 =3*2 = 6 line segments
the third figure has 3+3+3 = 3*3 = 9 line segments
the fourth figure has 3+3+3+3=3*4=12 line segments...
so it is clear that:
the 20th figure has 3*20=60 line segments.
Answer: 60
Let be be Beth, bi be Bill, and e be edie. Then:
1/be + 1/bi +1/e=1/12
1/bi + 1/e=1/15
10/be +10/bi +10/e+5/be+5/bi=1
Solve for be, bi, and e
