Pablo started with line A B ↔ AB A, B, with, \overleftrightarrow, on top and point C CC and constructed F G ↔ FG F, G, with, \overleftrightarrow, on top through point C CC. A A B B C C E E D D F F G G Which two statements, if true, guarantee that F G ↔ FG F, G, with, \overleftrightarrow, on top is perpendicular to A B ↔ AB A, B, with, \overleftrightarrow, on top?

answer:

c 60% on edg

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

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
