Answer:
Step-by-step explanation:
In triangle ABC, OA = OB = OC = 10 in. These segments are radii of sircumscribed circle. So, R = 10 in.
The sum of all interio angles is 180°, so
m∠C=180°-35°-65°=80°
Use the sine theorem,
Thus,
Therefore,
Describe the symmetry of the figure. Identify lines of symmetry, if any. Find the angle and the order of any rotational symmetry
