Is there a diagram?
yeah I was about to ask that
where is m?
when I clicked on it, it said provide username and password, so i can't help with this i'm sorry
that doesn't have an m on it
yupp there is no M
i think its suppose to be the M(measure) of angle R and Measure of angle S
I was thinking that to.. hold on let me see if I can get this..
so T would be 120 too?
120 Is not a choice
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
exactly what he did, ya'll was going to fast for me lol
i dont understand why only U and S are the only congruent ones though
why not the other two?
look at the pic. the sides of u and s are the same
|dw:1359136561728:dw| You are given just these sides congruent, right?
oh and angle T shares different sides from angle S
I meant R not S
Now draw a diagonal RS. |dw:1359136632967:dw|
Okay that makes more sense now then Thank you all!!!
|dw:1359136676205:dw| Diagonal RS is congruent to itself. So triangle RUT and triangle RST are congruent, and by corresponding parts, angle U and S are congruent.
|dw:1359136772891:dw| 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.
the correct answer is 40 100%
