Answer:
<6 = 60 degrees, <7 is 50 degrees, <8 is 70 degrees
Step-by-step explanation:
Angle 6 is 60 degrees because of the alternate interior angles theorem.
Angle 7 is 50 degrees, also because of the alternate interior angles theorem.
Now, the three interior angles of a triangle should add up to 180 degrees. That means:
60 + 50 + <8 = 180
<8 = 70 degrees
<6 = 60
<7 = 50
<8 = 70
