The length of the side BC is 6√3 inches
Step-by-step explanation:
Let us revise the sine rule
In Δ XYZ
- The side XY is opposite to angle Z
- The side YZ is opposite to angle X
- The side XZ is opposite to angle Y
- The sine rule is
In Δ ABC
∵ m∠A = 60°
∵ m∠C = 30°
∵ AB = 6 inches
- By using the sine rule
∵ AB is opposite to ∠C
∵ BC is opposite to ∠A
∵
∴
- By using cross multiplication
∴ BC × sin(30) = 6 × sin(60)
∵ sin(30) =
and sin(60) =
∴
BC = 6(
)
∴
BC = ![3\sqrt{3}](https://tex.z-dn.net/?f=3%5Csqrt%7B3%7D)
- Multiply both sides by 2
∴ BC = 6√3
The length of the side BC is 6√3 inches

Answer:
y = (12 - 4x)/5
Step-by-step explanation:
5y = 12 - 4x
y = 12/5 - 4x/5
y = (12 - 4x)/5
It is A because y=20x-5 and so it goes up and to the right
