Answer:
x = 8
Step-by-step explanation:
6(x-8)= x- (8)
6x - 48=x - 8
6x- 48 + 48 = x - 8 + 48
6x = x + 40
6x - x = x + 40 - x
5x = 40
5x/5 = 40/5
x = 8
Hope it helps! :)
First we use sin(a+b)= sinacosb+sinbcosa
and cos(a+b)=cosa cosb -sinasinb
tan(x+pi/2)= sin(x+pi/2) / cos(x+pi/2)
and sin(x+pi/2) = sinxcospi/2 + sinpi/2cosx =cosx,
<span>cos(x+pi/2) = cosxcospi/2- sinxsinpi/2= - sinx,
</span> because <span>cospi/2 =0, </span>and <span>sinpi/2=1
</span><span>=tan(x+pi/2)= sin(x+pi/2) / cos(x+pi/2)= cosx / -sinx = -1/tanx = -cotx
</span>from where <span>tan(x+pi/2)=-cotx</span>
558 divided by 23 equals
24 with a remainder of 6
It would just be -14 still
