8. Jonathan drove 100 miles to see his grandmother. If he drove at a speed of 50 miles per hour, then how many hours did it take him to
get to his grandmother's?

It would take Jonathon 2 hours to arrive at his grandmothers house.

Step-by-step explanation:

If he's driving at 50 miles per hour, it would take him 2 hours to drive 100 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
