Answer: sin = ±
Step-by-step explanation:
We very well know that,
cos2A=1−2sin²A
⟹ sinA = ±
As required, set A = & cos a=
,thus we get
sin =±
∴ sin =±
= ±
since ,360° < <450°
,180° < <225°
Now, we are to select the value with the correct sign. It's is obvious from the above constraints that the angle a/2 lies in the III-quadrant where 'sine' has negative value, thus the required value is negative.
hope it helped!

Step-by-step explanation:
Let , a reflection over the x-axis consists in the following operation:
If we know that and
, then the points translated over the x-axis are
and
, respectively. The most precise description of the shape is a rectangle for the following facts:
1) and
.
2) and
have the same x-component.
3) and
have the same x-component.
4) and
have the same y-component.
5) and
have the same y-component.
A representation of the shape is included below as attachment.
