Plz answer me the right answer
2nd one and 3rd one plz

ii)

y = 50 °

x = 100°

iii)

y = 30°

x = 120°

Step-by-step explanation:

ii) base angles on an isosceles are equal.

angles on a straight line sum to 180°

iii) opposite angles are equal

base angles on an isosceles are equal

angles in a triangle add up to 180°

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
