Who is correct?

show me what steps you took that leads to the answer ​

GAIL IS CORRECT

Step-by-step explanation:

AS IF WE GET ONE ANGLE WE CAN SOLVE OTHER ANGLES WITH ALTERNATIVE ,CORRESPONDING,LINEAR,VETICALLY OPPOSITE .

DO BY 1 ANGLE WE CAN FIND ALL ANGLES

Angle 1,4and3,2 is equal.

Angle 3,6and 4,5 is equal.

Angle 5,8 and 7,6 degree are equal in magnitude and Visa versa

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.
