# Given that the measure of ∠CBE is 135° find the measure of ∠BED. Assume that lines L and M are parallel A) 45° B) 55° C) 90° D) 135° ?

Answer is D. These angles are known as alternate opposite angles and when a line cuts two parallel lines, alternate opposite angles are always equal. Hence

Since lines L and M are parallel, ∠CBE and ∠BED are corresponding angles. Corresponding angles are equal when two parallel lines are intersected by a transversal. Therefore, since ∠CBE is 135°, ∠BED is also 135°. Therefore, the answer is option D) 135°.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
