ILL GIVE BRAINLEST PLEASE ANSWER WITH WORK :)

Adjacent, x = 100

Step-by-step explanation:

80 and x are on a straight line. Straight lines = 180 degrees. 180 - 80 = x

Vertical angles are opposite of each other, not next to each other.

Vertical

X = 100

Step-by-step explanation:

The lines are vertical because the lines intersect and create two opposite angles.

When it comes to finding x, there are two possible methods. First subtract 180 - 80. When there is a straight line its angle is 180. Since x and 80 share the same line, 180 - 80 means that the x has the other 100.

Also, when lines are vertical like this, two angles are the same. For example, if you look at 80 and go vertically to the next angle, it would also be 80. The angle next to 80 is again 100 because the line is 180. The 100 is x’s vertical angle partner, so x is also 100.

Therefore, x is 100!

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
