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:
coordinates of A are (11/2, -3/2)
Step-by-step explanation:
midpoint = M(5, −4)
start point = A(6, 1)
endpoint = B(x, y)
equation :
x = m1 × x2 + m2 × x1 y = m1 × y2 + m2 × y1
_____________ _____________
m1 + m2 m1 + m2
x = (1 × 6) + (1 × 5) y= (1 × 1) + (1 × -4)
_____________ ____________
1 + 1 1 + 1
x = (6+5 )/ 2 = 11 / 2 y = (1+(-4))/2+(1-4)/2 = -3/2
∴coordinates of A are (11/2, -3/2)
