High School Math: Lines and Angles I have a simple high school math questions about intersecting lines. However, I was unable to answer this question. 



I thought the answer should be "D" since I really don't see the questions are giving the answer. Please help.
Since the lines meet to the right,

$$2x+3x&gt;180^{\circ}\implies{}x&gt;36^{\circ}.$$

Hence Quantity $A$>Quantity $B$, which is option A.
That is like two lines: $3x+2x=5x$. There are two angels on the left side. Just look only at them. Do not think about left angels. The angel $3x$ and the angel $2x$ are more than $180$ degrees.
