Asmall jet can fly 1,072 miles in 4 hours with a tailwind but only 848 miles in 4 hours into a headwind. find the speed of the jet in still air and the speed of the wind.

Plain still in air = 240

Air current = 28

Step-by-step explanation:

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0
