by pythagorean formula, the last side is √(61)
by cos rule
cos A

A = 39.81
The answer is 600 because of the miles
Answer:
4.2π cm ≈ 13.19 cm
Step-by-step explanation:
The length s of an arc of a circle with radius r and central angle θ (in radians) is ...
s = rθ
Here, we have ...
s = (5.6 cm)(3π/4) = 4.2π cm ≈ 13.19 cm
So it would equal to 8/10 and divide by 2 which you would get 4/5
