The polygons below are similar find the value of x and y

Step-by-step explanation:

Angle corresponds to the complement of the in the bigger triangle. See diagram in attachment.

This implies that,

Also since the triangles are similar, the sides are in the same proportion.

This implies that,

We multiply both sides by 15 to get,

We divide through by 3 to get,

The correct answer is D

equal to

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
