Zinaida [17]
2sinxcosx - sin(2x)cos(2x) = 0 

<span>Part I </span>
<span>The double angle identity for sine states that sin(2x) = 2sinxcosx </span>
<span>Thus we get: </span>
<span>sin(2x) - sin(2x)cos(2x) = 0 </span>

<span>Part II </span>
<span>sin(2x)(1 - cos(2x)) = 0 </span>

<span>Part III </span>
<span>Either sin(2x) = 0 or </span>
<span>1 - cos(2x) = 0 </span>
<span>=> cos(2x) = 1 </span>

<span>For sin(2x) = 0, this is true for </span>
<span>2x = n(pi) where n = 0, 1, 2, .... </span>
<span>x = n(pi/2) </span>

<span>For cos(2x) = 1, this is true for </span>
<span>2x = n(pi) where n = 0, 2, 4, .... </span>
<span>x = n(pi/2)

Step-by-step explanation:

4x + 12° = 64° ( vertically opposite angle )

4x = 64° - 12°

4x = 52°

x = 52° / 4

x = 13°

hence the value of x is 13°
