Simplify as far as possible.13cos (180° + x)sin (360° - X)sin (360° + x)cos (180° - x)
1 answer:
Answer:
See below
Step-by-step explanation:
cos (180 + x) = - cos x
sin (360 + x) = sin x
sin 360 - x) = -sin x
cos (180 - x) = - cos x
3cos (180° + x)sin (360° - X) = -3cos x (- sin x) = 3 cosx sinx
sin (360° + x)cos (180° - x) = sin x (- cos x) = -sinx cosx
3cos (180° + x)sin (360° - X)sin (360° + x)cos (180° - x)
= 3 cosx sinx (-sinx cosx) = -3 (sin x)^2 (cos x)^2
I am not sure what the question really is, but hopefully the above can steer you in the right direction.

Y=kx+b
line is perpendicular y=1/3x+6⇒ k=-
=-3
so line y=-3x+a
this line that passes through (-9,12)⇔x=-9, y=12, so 12=-3(-9)+a
12=27+a
a=12-27
a=-15
y=-3x-15
