Help pls !! Eliza volunteers at a nearby aquarium where she tracks the migratory patterns
of humpback whales from their feeding
grounds to their breeding grounds. She
recorded the distance traveled by the
whales each day for a 7-day period at
the start of their migration. Based on
Eliza's data, about how long will it take
the humpback whales to travel the
3,100 miles to their breeding grounds?

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.

47 - 90 = 43

43 - 180 = x

x = 137
