ANYONE PLEASE HELP ME BECAUSE I HAVE TO PASS THIS LATER AT 10PM I DON'T HAVE MUCH TIME LEFT:( ​

Again, I'm really not sure if this is right, and please tell me where I got it wrong if I did.

I really hope this helps, and I feel really bad when someone asks me to help and I can't :((

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
