Answer:

Step-by-step explanation:
To find the <u>unit rate,</u> we need to find out how much distance does the cyclist travel in 1 second. For that, we need to use the unitary method. A unitary method is a method that determines the unit rate of an object.
<u>Note:</u> Since the cyclist travels at a <u>constant rate</u>, unitary method can be used.


<u>Divide both sides by 25:</u>

10 weeks, 10 times 2 is 20, and 5 times 10 is 50, divided by 2 is 25, add 20 to 25 which is 45

Answer:
135 degrees
Step-by-step explanation:
- Angle CBD is the sum of angle ABC and angle ABD, so we find these first
- An Isosceles triangle has 2 equal sides and 2 equal angles
- Isosceles triangle theorem tells us that the 2 equal angles are respectively opposite the equal sides
- Since triangle ABC has sides AB=AC, then angle ACB = angle ABC
- So knowing that angles of triangle add up to 180, then
- Now we do the next triangle to get ABD
- Since triangle ABD has sides AB=BD, then angle BDA = angle BAD
- So knowing that angles of triangle add up to 180, then
- Now we said, angle CBD is the sum of angle ABC and angle ABD, so
