Answer:

75 degrees

Step-by-step explanation:

Since lines A and B are parallel you can assume that angle 1 and angle 5 will be the same measurement. (You can see it better if you remove the other line)

What is the arc measure of BDC in degrees?<br> (4k + 159)<br> P<br> (2k + 153)

<h2>Explanation:</h2><h2></h2>

The diagram is missing but I'll assume that the arc BDC is:

$(4k + 159)^{\circ}$

And another arc, let's call it FGH. measures:

$(2k + 153)^{\circ}$

If those arc are equal, then this equation is true:

$(4k + 159)^{\circ}=(2k + 153)^{\circ} \\ \\ (4k + 159)=(2k + 153) \\ \\ \\ Solving \ for \ k: \\ \\ 4k-2k=153-159 \\ \\ 2k=-6 \\ \\ k=-\frac{6}{2} \\ \\ k=-3$
