Several students made comments about this image. which comment is true? “if i know the measures of a and b, i can subtract those measures from 180 to find the measures of the other two angles.” “if i know the measure of c, i can find the measure of angle a because they are the same.” “if i know the measures of angles c and b, i can find the measures of a and d.” “if i know the measure of angle a, i can find the measure of angle d by subtracting from 180.”
