The line of reflection will (always, sometimes, never) be the perpendicular bisector between a preimage and it’s reflected image.

Step-by-step explanation:

line of reflection: a fixed line directly in the middle of the pre-image and the reflected image.

perpendicular: two lines meeting at a 90 degree angle

bisector: line that divides something into two equal parts

pre-image: the original figure before any transformation or translation has been made

reflected image: the original image after being reflected across the line of reflection.

Is the line of reflection a line running perpendicular, directly in the middle of the pre-image and the reflected image? Yes, always would be my answer.

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

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
