Answer: see proof below
<u>Step-by-step explanation:</u>
Given: A + B + C = π → A = π - (B + C)
→ B = π - (A + C)
→ C = π - (A + B)
Use Sum to Product Identity: sin A - sin B = 2 cos [(A + B)/2] · sin [(A - B)/2]
Use the following Cofunction Identity: cos (π/2 - A) = sin A
<u>Proof LHS → RHS:</u>
LHS: sin A - sin B + sin C
= (sin A - sin B) + sin C

Step-by-step explanation:
The value of x in (1/6)/2 = x/3 is 1
<h3>How to solve for x?</h3>
The equation is given as
(1/6)/2 = x/3
Cross multiply in the above equation
x * 2 = (1/6) * 3
This gives
x * 2 = 1/2
Cross multiply
x = 2 * 1/2
This gives
x = 1
Hence, the value of x in (1/6)/2 = x/3 is 1
