Ornithologists have determined that some species of birds tend to avoid flights over large bodies of water during daylight hours. it is believed that more energy is required to fly over water than land because air generally rises over land and falls over water during the day.
a. bird with these tendencies is released from an island that is 6 km from the nearest point
b. on the shoreline, flies to a point
c. on the shoreline, and then flies along the shoreline to its nesting area
d. assume that the bird instinctively chooses a path that will minimize its energy expenditure. points b and d are 13 km apart. (round your answers to two decimal places.)

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29

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.
