Answer:
53.62 m
Step-by-step explanation:
Length of arc = θ/360 × 2πr
r = XZ = 12 m
m<XYZ = 180 - 108 = 72° (angles on a straight line)
θ = 85° + 72° + 108° = 265°
Length of arc YWV = 256/360 × 2 × π × 12
= 53.6165146 ≈ 53.62 m (nearest hundredth)
2⁻³² = (-2²)⁻⁶ • (2⁻⁵)⁻⁴
2⁻⁵ = (2²)² • (2³)⁻³
2⁸ = (-2⁻⁴)⁻² • (2²)⁰
1 = 2⁴ • (2²)⁻²
x=y/9
9x^2-6x+6x-4
