Answer:
10. 123º
13. 65º
Step-by-step explanation:
For number 10, a straight line is equal to 180º so all we have to do is subtract 57 (the number that we're given) from 180
For number 13, vertical angles are always congruent (the same) so we know that it's 65º

Answer:
Step-by-step explanation:
hello :
the equation of the circle is : (x-5)²+(y-8)² =9²
Answer:
The equation e = 4 h can be used to describe this situation.
Jonah earns $20 to babysit for 5 hours.
Step-by-step explanation:
When Jonah babysits one hour, he earns $7.50.
looking at the graph we see at 1 hour he earns 4 dollars false
The equation e = 4 h can be used to describe this situation.
The slope is 4 so y = 4x e = 4h would also work true
Jonah earns $20 to babysit for 5 hours.
Using our equation from above
e = 4*5 = 20 true
The number of hours Jonah works depends on how much he earns.
This would be false
The dependent variable is on the y axis. The amount he earns depends on how much he works
