Cynthia is constructing a circle inscribed in a triangle. she has partially completed the construction, as shown below. what should be her next step in the construction? (triangle abc is shown with arc markings on side ab and bc and two intersecting arc markings across from angle b.) a. connect vertex b to the arc markings to complete the angle bisector. b. use a straightedge to find the angle bisectors for angles a and b. c. connect three arc markings together to form the triangle. d. use the arc markings to determine the radius to construct the circle.

option: A is correct.

Step-by-step explanation:

According to the construction defined in the question we see that we will get geometry as attached to the answer (Figure 1)

Since by connecting the vertex B to the arc markings he is trying to find out the first angle bisector i.e. angle bisector of angle  B and geometry will look like a figure as attached to the answer(figure 2).

Hence, option A is correct.

the answer is 375 miles

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
