God I hate geometry. Please, tell me that one of you can help me with this problem...?

Given: m(angle)J + m(angle)H + m(angle)JKH = 180
Prove: a) m(angle)1 = m(angle)J + m(angle)H
b) m(angle)1 > m(angle)J

Here is a link to the diagram: http://bbsbaby920.tripod.com/

Please help, I have no idea what they're asking for here.

It's pretty much what they said:

Looking at your image…

The first proof is asking you to prove why the measure of angle1 is equal to the measures of angles J and H combined. The second proof will follow from the first one fairly easily, since it is asking you to prove that angle 1 is greater than angle J.

Logically, because Angle J + Angle H = Angle 1, Angle J will be less than Angle 1. You just need to prove this.
