Answer:
10.3
Step-by-step explanation:
So first you get the angle of T which is 25 degrees
The you use the law of sine
Then you get s = 10.34763268
Round to nearest tenth
s = 10.3

5). 11 6/15
7). 11 5/6
9). 9 7/8
11). 17 1/2
13). 22 7/12
Answer:
∠ ABC = 22°
Step-by-step explanation:
OA = OB ( radii of circle )
Then Δ OAB is isosceles with base angles congruent , that is
∠ OBA = ∠ OAB = 17x
The sum of the 3 angles in the triangle sum to 180°
17x + 17x + 11x = 180
45x = 180 ( divide both sides by 45 )
x = 4
Then
∠ OBA = 17x = 17(4) = 68°
BC is a tangent so ∠ OBC = 90°
∠ ABC = 90° - ∠ OBA = 90° - 68° = 22°

Answer:
5.5 miles per hour
Step-by-step explanation:
Since he travels a total of 55 miles in 10 hours, you need to divide.
55/10 = 5.5
total hours/total miles = miles per hour
