i think its suppose to be the M(measure) of angle R and Measure of angle S

Sorry, look at the new picture. Only angle U and S are congruent.

But you can find out what the sum of all the angles is.

100+100+120+t=360?
320+t=360
t=40

they all need to = 360 and u and s are conruent ao 100+100+120 =320 and 320+40=360

i dont understand why only U and S are the only congruent ones though

You are given just these sides congruent, right?

oh and angle T shares different sides from angle S

Now draw a diagonal RS.

Diagonal RS is congruent to itself.
So triangle RUT and triangle RST are congruent, and by corresponding parts, angle U and S are congruent.

If you draw diagonal US, even though US is congruent to itself, there are no triangles that you can prove congruent. So you don't know anything about angles R and T being congruent.
