Answer:
B, it's the only plausible one. A is wrong because the value would be above 180°
Answer:
2.5 inches
Step-by-step explanation:
To find the radius when you only have the diameter then you divide the diameter in half and you get your radius
5/2= 2.5
Since s and t are complimentary, that means ∠s + ∠t = 90
From the picture, we also know that ∠t + ∠LGM = 90
Set them equal to each other:
∠s + ∠t = ∠t + ∠LGM, solve:
∠s = ∠LGM
Now using the fact that tangent = opposite/adjacent:
tan (∠s) = 
tan (∠s) = 
Set them equal to each other to get:
= 
Solve:

Part B:
Using tan (∠s) = 
We get:
meters
Hope that helps!
