Answer:
Perpendicular bisector theorem
Step-by-step explanation:
The illustration of the theorem is:
If point B is a perpendicular bisector of Line AC and the length of AC is 10cm
Then

Where
--- Perpendicular bisector
So, the equation becomes



Recall: 

<h2>sum of angle of triangle is 180°</h2>
<h2>A+B+C = 180 </h2>
<h2>38°+75°+ X = 180°</h2>
<h2>113° + X = 180°</h2>
<h2>X = 180° -113</h2>
<h2>X = 67°</h2>
Answer: The area is 12.55
