Find the ratio a:b if it is givin that a/3 = b/4

Step-by-step explanation:

Cross multiply the givens

3b = 4a         Divide both sides by 4

3b/4 = a        Now divide by b

3/4 = a/b

This can be written as

3:4 :: a:b

a: 1/6, j: 1/4

hope it you

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
