Looking at your picture, the side across from angle 1 is equal to the length of the side across from 24 degrees. So what does that tell you about angle 1? Do you know the rules of sides and angles?

OpenStudy (imstuck):

So sorry. Had to delete that because it wasn't where I actually wanted to start. Anyways, do you know about the relationship between angles when the sides across from them are congruent?

OpenStudy (anonymous):

no. and your ok

The sides with the two little lines through them are congruent to one another; they are the exact same length. That means that the angles across from those 2 equal sides are also equal. So what is the measure of angle 1 then?
