Angle d has a measure between 0° and 360° and is coterminal with a –920° angle. what is the measure of angle d?

 The required measure of angle D is 160°.

Step-by-step explanation:  Given that angle D has a measure between 0° and 360° and is co terminal with an angle of measure –920°.

We are to find the measure of angle D.

We know that any two co terminal angles have measures that differ by a multiple of 360°.

So, to find the measure of angle D, we proceed as follows :

Since 0° < 160° < 360°, so the required measure of angle D is 160°.

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
