In the diagram of △KLM below, m∠L=70, m∠L=50, and MK is extended through N. What is the measure of ∠LKN?

Apositive number a or the same number a increased by 50% and then decreased by 50% of the result?

Which will form a composite function?

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
