Two hikers started at the same location. One traveled 2 miles east and then 1 mile north. The
other traveled 1 mile west and then 3 miles south.
At the end of their hikes, how many miles apart are
the two hikers? [The use of the accompanying grid
is optional.]

hola

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

pi x^2

step-by-step explanation:

pi times x squared
