Answer:
D
Step-by-step explanation:
To answer this question, we have to define to bisect an angle:
To bisect an angle is to divide it into two equal parts, we can call those as congruent parts because these have the same area.
So it is crucial: we need to keep it proportionally divided when we start to construct an angle bisector.
Examining the alternatives, there is only one correct:
--
D. So now let's place the compass needle on the vertex of the angle, and draw an arc across both legs of the angle. True
The reason to proceed this way as our first step is the proportional division made by the inner line that bisects the angle. Thus in the first step, we pave the way to trace another arc in the middle of the inside area. Done with the same width and compass needle on the marks. Finally, the line to vertex crossing the mark.

Answer:
min
Step-by-step explanation:
In order to solve this problem, we must subtract the times he has already used from the time he has available, so we get:
we can start solving this subtraction by turning all of the numbers into improper fractions so we get:
next, we can find a least common denominator. In this case it will be 4, so we need to turn all denominators into a 4, so we get:
and now we can subtract the numerators and copy the denominators so we get:
which can now be turned into a mixed number by dividing 47/4 which yields 11 with a remainder of 3, so the mixed number is:
min
and this is the amount of time he has available to solve the las problem.
