It would be 30/48 but you still have to simplify it
5/8 is the answer
r and s are parallel
given ∠4 = ∠5 ( these are congruent interior alternate angles )
between the lines r and s, hence
r and s are parallel lines
Answer:

Step-by-step explanation:
we know that
An exterior angle of a triangle is equal to the sum of the opposite interior angles.
see the attached figure to better understand the problem
so
∠DEF=∠ECD+∠CDE
substitute the given values

solve for x
Combine like terms

Group terms



Find the measure of angle CDE

substitute the value of x

One over three is the answer 1/3
