Determine the scale factor to determine if STUV ~ LMNO.
Yes, the figures are similar. The scale factor is 78/59
Yes, the figures are similar. The scale factor is 10/7
Yes, the figures are similar. The scale factor is 78/54.6
No, the figures are not similar.

what is the original number? you forgot to add it.

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.

the anwser is x< -17/2
