A searchlight rotates through one complete revolution every 36 seconds. How long does it take the light to rotate through 90°?

1 second

1 full revolution=360

4seconds=360degrees

how many seconds are 90 degrees

4:360=x:90

4/360=x/90

simplify

1/90=x/90

1=x

the answer is 1 second

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
