Find the ratio in simlest form of 221 to 289​

Step-by-step explanation:

To simplify the ratio of 221:289, you must find a common factor between the two numbers. In this case, they share 1 and 17. Use 17, and divide both numbers by it. You'll end up with 13:17 as your simplified ratio.

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.
