Divide both sides by -3
y + 5 = -15/3
Simplify 15/3 to 5
y + 5 = -5
Subtract 5 from both sides
y = -5 - 5
Simplify -5 - 5 to -10
y = -10

Answer:
1 ) sin 165°
2 ) cos 330°
3 ) Tan 157.5°
4 ) 
Step-by-step explanation:
1 )
Given expression is 
We know that 


So the first expression is sin (330/2)° =sin 165°
2 )
GIven expression is 
We know that 
So the result is cos 330°
3 )
Given expression is 
We know that 
Also we know that sin2x = 2sinxcosx
So The numerator becomes
. and the denominator becomes as 

So the result is Tan 157.5°
4 )
Given expression is 
We know that 

So the result is 
No, the data has no constant
