There are 10fish inside a lake and the 3 fish's get eaten by a shark
and the 2 fish don't no there way
and 1 fish get hunted by a person

how many fish's left?

452,489 to the nearest thousand is 452,000

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

5x+10 is the correct one

hope this
