∠A and ∠ B ∠B are vertical angles. If m ∠ A = ( 5 x − 4 ) ∘ ∠A=(5x−4) ∘ and m ∠ B = ( 2 x − 1 ) ∘ ∠B=(2x−1) ∘ , then find the value of x.

x=1

Step-by-step explanation:

vertical angles are equal

therefore a=b

5x-4=2x-1= 3x=3

x=1

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
