find the value of x

x=7

Step-by-step explanation:

We know that 3x+1 = 22 since AH is the perpendicular bisector

3x+1 =22

Subtract 1 from each side

3x+1-1 =22-1

3x =21

Divide each side by 3

3x/3 =21/3

x =7

Looking at the two right triangles that have been created, we can see that the hypotenuses of both triangles are congruent. The triangles have one side in common and equal, thus the bases of each triangle must also be equal. To solve for x, all we have to do is set the bases equivalent to each other.

3x + 1 = 22

3x = 21

x = 7 units

Hope this helps!! :)

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
