In parallelogram klmn, m∠klm=100°. identify m∠knm.

m∠KNM = 100°

Step-by-step explanation:

Because this is a parallelogram, we know that lines KL and MN are parallel, as are lines NK and LM. So, we can use the Opposite Interior Angles Theorem to identify m∠KNM.

The Opposite Interior Angles Theorem states that, when two parallel lines are intersected by a transversal, their opposite interior angles are congruent. The interior angle that is opposite ∠KLM is ∠KNM. Therefore they must have equal measures.

Since m∠KLM = 100°, m∠KNM must also equal 100°.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
