The inscribed angle is 20 so its arc is 40. The central angle, angle 1, has the same arc as the inscribed angle and the central angle is equal to its arc so angle 1 is 40

@Mertsj So wouldn't i be right if it was this way, and your saying the triangles are both the same

I said the triangles look the same. That does not make them the same. You have to assume that the radius is parallel to the chord. But according to the given information, that is not true.
