To find the speed of a car, use the expression d divided by t, where d represents the distance and t represents time. Find the speed of a car that travels from Clinton to Greenville in 2 hours.

Speed = distance / time

Let the distance between clinton and greenville be x

d= distance= x km

t= time = 2 hr

S= d / t

S= x / 2hr

So the speed is x / 2 km/ hr

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

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
