Answer:
3) 84°
Step-by-step explanation:
The angle formed by a chord and a tangent measures half of the intercepted arc.
m<A = (1/2)m(arc) = (1/2) * (168 deg) = 84 deg
Answer:
The explicit formula for f(n) is:

Step-by-step explanation:
The explicit formula is described by the following geometrical progression:

1.x+4y- - 67 =-1
x+4y+67=-1
x+4y=-1-67
X+4y=-68
2.2x-y+2z=-7
2x=-7+y-2z
x=-7/2+1/2y-z
x=-7/2+1/2y-z, y€R, z€R
Warning: I don’t have the € and R
3.-x+2y- -43=5
-x+2y+43=5
-x+2y=5-43
-x+2y=-38
x-2y=38
Hope this helps!
