Answer:
C
Step-by-step explanation:
C is only right answer among a to d
Sin⁻¹ √2 = 1/√2 = 1(√2) / (√2)(√2) = √2/2
Try, pls, this:
1. Note, that for the both points x₁=x₂=-5, it means line is vertical, that is equation form is x=a, where a=number.
2. The number for 'a' may be extracted from points, a=-5.
3. Equation for line is x=-5.
The solution to the problem is as follows:
<span>cos2A - cos4A = -2 sin(6A/2).sin(-2A/2) = +2 sin(3A).sinA
and
sin4A - sin2A = 2 cos(6A/2).sin(2A/2) = 2 cos(3A).sinA
Hence RHS = (cos(2A)-cos(4A))/ (sin(4A)- Sin(2A)) = sin 3A / cos 3A = tan 3A = LHS

Move variable to the left. -w= -10+ 4W
-w-4W =-10
Collect like terms
-5w=-10 divide both sides by 5
