Julio's mother bought 2 and 1/2 pounds of bananas on monday. julio ate 1/4 of the bananas before he went to bed. on tuesday, julio ate 1/3 of the remaining bananas. how many pounds of bananas did julio eat on tuesday?

The answer to this question would be: B. JK and LM meet at a right angle.

The reversed T symbol in this question means "perpendicular". That means the JK and LM line have 90-degree angle difference. A straight angle is 180 degree and right angle mean 90 degrees.
A perpendicular line should be in the same plane and intersect each other.
