Motor riders Vladimir and Varya started their rides from two points that are 160 miles apart. Laika, Vladimir's pet parrot started chasing Vladimir's motorcycle and overtakes him and meets Varya. Then Laika flew back towards Vladimir. The parrot then started flying back and forth between the two riders. The parrot flew at the speed of 25 mph, while Vladimir and Varya's speed was 20 mph. What was the total distance that Laika flew in miles​

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

two data sets with the same median will not have the same varaibility

step-by-step explanation:

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

3 is greater then both of those numbers
