Below are two parallel lines with a third line intersecting them.
I need help solving for x

its a 50 degree angle i think.

Step-by-step explanation:

its a smaller size in scale of the bigger one.

50

Step-by-step explanation:

Actually there is not much this to explain.

Since those lines are parallel and there is a straight line going through them the degrees are exact same.

Hope it helps. Please let me know if you have any questions.

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510

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
