To find the measure of angle OPQ, we have two equations...
y+5x-17=180 because angles OPN and OPQ are supplementary...
AND
x+17+2x-4+y=180 because the total degrees of a triangle must add up to 180.
The equations...
5x+y=197
3x+y=167
solce the system of equations...
x=15
y=122
Since we wanted to solve for y, 122 is the answer.
The measure of angle OPQ is 122.

Answer:
Step-by-step explanation:
The standard equation for circle is
where point (a,b) is coordinate of center of circle and r is the radius.
______________________________________________________
Given
center of circle =((-2,3)
let r be the radius of circle
Plugging in this value of center in standard equation for circle given above we have
Given that point (1,2 ) passes through circle. Hence this point will satisfy the above equation of circle.
Plugging in the point (1,2 ) in equation 1 we have
now we have value of r^2 = 10, substituting this in equation 1 we have
Thus complete equation of circle is
The question is incomplete. Here is the complete question:
A contractor has two choices for billing a completed job.
· $500 flat rate, regardless of the number of hours worked
· $20 per hour worked
The graph shows the relationship between pay per hour and number of hours worked for both scenarios.
What is the solution to this system of equations, and what does it mean to the contractor?
A.The solution (0, 20) tells the contractor the minimum amount that can be charged.
B.The solution (0, 500) tells the contractor the maximum amount that can be charged.
C.The solution (25, 20) tells the contractor the number of hours on a job where the hourly rate is the same for both billing options.
D.The solution (20, 25) tells the contractor the number of hours on a job where the hourly rate is the same for both billing options.
Answer:
The graph is attached below.
C.The solution (25, 20) tells the contractor the number of hours on a job where the hourly rate is the same for both billing options.
Step-by-step explanation:
As per the graph, the x-axis represents the number of hours worked and the y-axis represents the rate in dollars per hour.
The hourly rate is given as $20.
The solution to the given lines drawn on the graph is the point of intersection of the two curves.
As we observe from the graph, the point of intersection of the two curves is at (25,20). The point tells the contractor that when the hourly rate is $20, then the number of hours worked will be 25.
So, when the hourly rate is same for both the billings, then the number of hours worked will be 25.
Hence, the correct option is (C).
