- AC is congruent to itself
- AC bisects angle BAD, so that angles BAC and DAC are congruent
- Both angles B and D are right angles, so they are congruent
This means triangles BAC and DAC are a pair of angle-angle-side triangles, so they are congruent to one another. Corresponding parts of congruent triangles are congruent, so the line segments BC and DC are congruent and have the same length.
Then
Let's turn this into a fraction using the given information we already have.
We want the denominator, or the bottom part of the fraction, to be 1 in order for us to have a unit rate.
This fraction can be simplified if we divide both the numerator and denominator by 3.
Numerator: 18/3 = 6
Denominator: 3/3 = 1
Now we have
Any number divided by 1 is equal to that number.
Thus, your unit rate is 6 miles per hour.
Have an awesome day! :)

Answer:
60 degrees counterclockwise
Step-by-step explanation:
One circle is 360 degrees.
If the circle is split into 6 pieces, (360/6 = 60), then each piece is 60 degrees, like in the example.
