We finally made it!  Finals are around the corner, and so is summer!  I can’t wait to ditch my backpack and head to the beach.  But first, I have to survive finals.  To review for Geometry, I’ve posted one of my favorite homework problems from a past unit below.

KL⎮⎮JM in isosceles trapezoid JKLM.  Find the values of x and y if m⦟J=(23x-8)º, m⦟K=(12y-13)º, and m⦟M=(17x+10)º.

m⦟J=m⦟M

23x-8=17x+10

6x-8=10

6x=18

x=3

m⦟J+m⦟K=180

23x-8+12y-13=180

61+12y-13=180

12y=132

y=11

I chose this problem because I was from one of the first units of the semester, and I didn’t remember that unit at all.  I thought that it would be nice to review since I had forgotten about it.
