Answer:
henc X = 30°
Step-by-step explanation:
here is the proof
when X=30° then
 sin2x = sin2×30
 =sin 60°
 = √3/2
or else,
 putting value of X = 30° then
sin2x= 2sinxcosx
 = 2×sin30°×cos30°
 =2×1/2×√3/2
 = 2√3/4
 = √3/2
hence proved sin2x= √3/2.
 
        
             
        
        
        
Normally, you would do whatever is inside of the parenthesees first then do the rest but we cant get any further so we remove the parenthasees by distrubtion
7a+6b-4(3a-3b)
-4(3a-3b)
a(b+c)=(ab)+(ac)
-4(3a-3b)=-12a-(-12b)
7a+6b-12a+12b
7a-12a+6b+12b
-5a+18b
that's the asnwer
        
             
        
        
        
Answer:      Overview. An angle is the union of two rays with a common endpoint. The common endpoint of the rays is called the vertex of the angle, and the rays themselves are called the sides of the angle.
