Answer:
Formula for Central Angle: θ = Arc Length×180°π×r
Central Angle Formula: s=r×θ
Double Angle Formula: (Has three) cos2θ= cos2θ−sin2θ sin2θ=2sinθcosθ tan2θ=2tanθ/1−2 tan2θ
Step-by-step explanation:
Answer:
45° and 12
Step-by-step explanation:
The sum of the exterior angles of a polygon = 360°
(8)
The polygon has n = 8, that is 8 exterior angles, thus
exterior angle = 360° ÷ 8 = 45°
(9)
The number of sides n is
n = 360 ÷ 30 = 12
