Lets O is the center of the circle and Lets A is a point cut on CD from O
mCD = m<COD
OA is perpendicular bisector of CD so OA = 1/2 CD = 1/2(12.7) = 6.35
Sin (DOA) = AD/OD = 6.35 / 9.06
Sin DOA = 0.7009
<DOA = 44.5°
<COD = 2 x 44.5°
<COD = 89°
mCD = <COD = 89°
Answer: 89°

Answer:
The distance cover by Noah in 1 hour to cover distance is 6.5 miles
Step-by-step explanation:
Given as :
The distance cover by Lin = 2
miles =
miles
The time taken to cover distance by Lin =
hours
<u>Again</u>
The distance cover by Noah = 8
miles =
miles
The time taken to cover distance by Noah =
hours
Let the distance cover by Noah in 1 hour = d miles
∵ The distance cover by Noah in
hours =
miles
∴ The distance cover by Noah in 1 hour = 
I.e d =
miles
or, d =
= 6.5 miles
So, The distance cover by Noah in 1 hour = d = 6.5 miles
Hence, The distance cover by Noah in 1 hour to cover distance is 6.5 miles Answer
