Answer :

SchwarzschildRadius
So,

Notice that there is a triangle with two of the angles given.  We know that the sum of any triangle's angles will always be 180°.  Thus, we can subtract the two given angles from 180, and that will give us the measure of angle ABC.

180 - 20 - 25 = 160 - 25 = 135

The measure of angle ABC is 135°.

The correct option is D.
