Find the measure of the given Angles show work.

acc to angle sum property of trianglesx+60+x+50= 90

2x = -20

x= -10

A= x+50= -10+50==40

B=x+60= -10+60=50/

constants mean the stopped points or the points on a graph that nothing is changing, hope this

step-by-step explanation:

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
