Hint: d= (x2 – Xı)2 + (y2 - yı)

can u follow me my buddy

I want friend

Step-by-step explanation:

d²= (x2 – Xı)²+ (y2 - yı)²

d²=(3+1)²+(1+1)²

d²=(16)+4

d=✓20

d=2✓5

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
