Answer:
x=8, x=4
Step-by-step explanation:
<u>Add 4 to both sides</u>
<u>Square root</u>
<u />
x - 6 = ±2
x = 8
OR x = 4
So, x=8 or x=4

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)
4/5= 4 x 2=8
5 x 2=10
5/8=5 x 3 =15
6 x 3= 18
