Find the equation of the line that passes through point c and is perpendicular to the line that passes through points a and b. graph the two lines in geogebra finding their point of intersection and verifying the angle between them

a(1,-8); b(3,2); c(9,-7)

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

it is c, trust i got your back lol

step-by-step explanation:

d 600 because 15*10*2=300

300+300=600
