If m∠1= 50°, find m∠8.

The correct answer is: So, ∠8=50°

SOLUTION:
HINT: Use the property of parallel lines angle rules.
Complete step by step solution:


Here we have 2 parallel lines M and l and 2 transversals  and  intersecting these
parallel lines.
Here it is given that 
(vertically opposite angles)
Now,   (corresponding angles)
Now take  2 parallel lines as  p and q and 2 transversals m and l  intersecting these
parallel lines.
So, we have  (corresponding angles)
So,
