Answer:
<h3>60°</h3>
Step-by-step explanation:
Given that:
- Circumference (C) = 6 units
- Arc length (A) = 1 unit
<u>Find the central angle (</u><u>θ</u><u>)</u>
Arc is some part of circumference; thus,
the equation of arc length =
A = θ/360 × C
θ/360 = A/C
θ = (360×A)/C
θ = (360×1)/6
θ = 360 ÷ 6
<h3>θ = 60° ✅</h3>
Central angle = 60°
