Problem Solving (PS) | Re: A non-symmetrical arrow point exists such that the angle of the back

Connect Point of angle A and angle C to form a triangle.

This also forms another smaller triangle with one angle as 105. The other two angles have to be 75.

Now you can notice that in the bigger triangle, sum of a , b, c will be 180 - 75 = 105. That's your answer - A
