Draw an angle with the given measure in standard position.
2. 60 degrees
3. -135 degrees
4. 450 degrees
5. -1125 degrees

 see graphs

Step-by-step explanation:

start at the origin and draw an arrow...

2) 60° counterclockwise = 60°

3) 135° clockwise (360 - 135) = 225°

4) one full ring counterclockwise plus (450 - 360) = 90°

5) three full rings clockwise plus (360(4) - 1125) = 315°

step-by-step explanation:

if the four friends split the cost, p, of the pizza evenly, then each friend pays one-fourth of the cost of the pizza.

the expression is   or  

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
