18. Answer: D
<u>Step-by-step explanation:</u>
First, find the measure of the missing angle.
65° + 57° + x = 180°
122° + x = 180°
x = 58°
Next, match up the angles with the opposite sides:
65° ⇄ Swim
58° ⇄ Bike
57° ⇄ Run
Lastly, put them in order from least to greatest:
57° < 58° < 65°
⇒ Run < Bike < Swim
The only multiple choice option that is correct is Bike > Run.

19. Answer: 22.3°
<u>Step-by-step explanation:</u>
D = 22.3°
The first column is x while the second is y. To find rate, you divide y by x. If each row has the same outcome, it is proportional.
First row:
9.00÷2= 4.50
Second row:
22.50÷5= 4.50
Third row:
31.50÷7= 4.50
There is a proportional relationship based off of the values.
So B, yes there is a constant of proportionality of $4.50.
Answer:
4
the fourth expression is a rational
All 3 angles have to add up to be 180 so the answer would be 90
Divide the value of "b" by 2 and then square it.
(b / 2)²
= (120 / 2)²
= (60)²
= 3600
Therefore the value of z is 3600. That's at least what I believe lol
