FORMULA:
Length of arc PQ = 2πrΦ/360°
ANSWER:
Using formula,
2 × 22/7 × 7 × 80/360
44 × 2/9
88/9ft or 9.7ft
The question is asking to complete the passage about the sum of angle of the exterior angles of an n-gon, one at each vertex, and i would say that it should be 360 degree. I hope you are satisfied with my answer and feel free to ask for more if you have question and further clarification
Answer:
X<4
Step-by-step explanation:
X/2<2 by subtracting 8 from both sides
Then you need to multiple by 2 and get
X<4
Group like terms , factor out common variable.
(xz+x) + (yz+y)
x(z+1) + y(z+1)
factor out (z+1)
= (z+1)(x+y)
= solution C.
