Answer 11

Since RA=RB we know the triangle is isosceles. Therefore angle A equals angle B.

Since RB||AB, then alternate interior angles are equal. So angle A equals angle 2. Also corresponding angles are equal. So angle B equals angle 2.

Since angle A equals angle B, then angle 1 must also equal angle 2
