If two lines are intersected by a transversal, and the alternate interior angles are equal, then the lines are parallel.
Conversely, if two lines are parallel, then the alternate interior angles formed by the transversal are equal.
So, Ray can made the conclusion that l and m are parallel because alternate interior angles are equal since m∠3 = m∠6.
Answer:
a) 
b) 
Step-by-step explanation:
If each curved path has 52% of the previous height this means that 
Then the radius of convergence is 0.52 and this is a geometric series.
The geometric series have the form:

Where
is the first term of the series and r is the radius of convergence.
In this problem
meters = 50 cm

a) Then the rule for the sequence is:

b) we must calculate
