In the figure below, \overline{BD}
BD
start overline, B, D, end overline and \overline{AC}
AC
start overline, A, C, end overline are diameters of circle PPP.
What is the arc measure of \stackrel{\Huge{\frown}}{DBC}
DBC
⌢
D, B, C, start superscript, \frown, end superscript in degrees?
^\circ
∘
degrees

Step-by-step explanation:

The picture of the question in the attached figure

step 1

Find the value of x

we know that

----> by central angle (Remember that C is the center of the circle)

so

solve for x

step 2

Find the measure of arc BC

we know that

The diameter divide the circle into two equal arcs of measure 180 degrees each

so

step 3

Find the measure of arc DBC

we know that

The measure of arc DBC is given by

we have

---> because BD is a diameter of circle P

substitute
