Answer:
<1= 135 degrees 
<4= 135 degrees
<6= 45 degrees 
Step-by-step explanation:
This is because angle two and 6 are corresponding angles. you would then subtract 180 from 45 because angle 6 and 4 are consecutive angles. This would give you 135 degrees. Then angle 1 and angle 4 are verticla agles, making them equal to each other.
