Answer:
m∠∅ = 2.25 radians
Step-by-step explanation:
A dog has been tethered with a lead of 20 feet which makes a path making an arc of 45 feet. We have to calculate the measurement of the angle ∅ in radians.
Since the formula to measure the length of arc = r∅
where r is the radius of arc
Therefore ∅ = Arc/radius
∅ = 45 /20 = 2.25 radians
