After you type in your equations and hit graph you notice that, if you are in the standard window, your parabola is cut off so you have to choose your "window" button to change the viewing window to see the whole graph. Then you would use your 2nd button and "trace" and "intersect" to find the points of intersection of the 2 graphs. The first point is at (-.90901, 16.81812) and the second point is at (5.9090909, 3.1818182). Graphing calculators are quite amazing!

A.Find the measures of the remaining angles of parallelogram KLMN. Justify each of the measures with a theorem.
Inga [223]

a.

<K = <M = 50 ...Opposite angels are congruent

<K + <L  = 180...Consecutive angles are supplementary

 50 + <L  = 180 so <L = 180 - 50 = 130

<L = <N = 130...Opposite angels are congruent

50 + <N  = 180 so <N = 180 - 50 = 130

b.

MN = LK = 7...Opposite sides are congruent

KN = LM = 10...Opposite sides are congruent
