Answer: A= 30° B= 60° C= 90°
Step-by-step explanation: All right triangles equal 180°, so all you have to do is add the two angles shown on the interior of the triangle already. For A, we already have 30° and for C we have 90°(because C is a right angle, which equals 90°), so you'd get a total of 120°. 180° minus 120° equals 60°, so that would be our answer for B.
