Answer:
60* and 30*
Step-by-step explanation:
If two angles are complementary then they will add up to be 90, or inversely, if two angles add up to be 90, then they are complementary. If you know one acute angle, you can calculate its complementary angle by subtracting 90 and the angle.
m<qrt and m<trv because complementary angles add up to 90 degrees :)
(x,y) = (0,231)
60:70
