Answer:
The basic idea behind copying a given angle is to use your compass to sort of measure how wide the angle is open; then you create another angle with the same amount of opening.
Step-by-step explanation: these are the steps
Using a straightedge, draw a reference line, if one is not provided.
Place a dot (starting point) on the reference line.
Place the point of the compass on the vertex of the given angle, ∠ABC (vertex at point B).
Stretch the compass to any length that will stay "on" the angle
The first person completes a job in 10 minutes and the second person completes the same job in 15 minutes. When they work together, they can do the job in 6 minutes.
This question pertains to the concept of rate of work. Work rate is generally described as the amount of work done per unit time. The first person completes the job in ten minutes, so their work rate is 1 job per 10 minutes. The second person completes in fifteen minutes, so their work rate is 1 job per 15 minutes.
When they work together, their rates of work add up. Therefore, the rate at which they complete the work together is (1 job/10 minutes) + (1 job/15 minutes).
Convert these rates to a common denominator (30) to simplify the calculation: (30 jobs/300 minutes)+(20 jobs/300 minutes) equals 50 jobs/300 minutes.
Therefore, together, they can do 50 jobs in 300 minutes. Hence, to do 1 job, they will need 300 minutes / 50 = 6 minutes.
