Answer with explanation:

In Quadrilateral A B CD

Diagonal BD bisects angle D.

→→ ∠A DB=∠ C DB

In ΔA DB and ΔC DB

1. AB= CB→→→→[Given]

 2. ∠A DB=∠ C DB-------[Given]

3. BD=BD ----[Common side]

⇒ ΔA DB ≅ ΔC DB→→→[S A S]

AD=DC→→→→[C P C T]

Option B:⇒ AD = DC

C is the circumcenter of APQR.<br> PC=3x+7, RC=5x-15, &amp; QC=51-X<br> x=[?]
amm1812

Answer:

x = 11

Step-by-step explanation:

C is the circumcenter of \triangle PQR

\implies PC=QC=RC (Radii of same circle)

\implies RC=QC

\implies 5x-15=51-x

\implies 5x +x=51+15

\implies 6x =66

\implies \: x =  \frac{66}{6}  \\  \\  \implies \:  \huge \:  \red{x = 11}

Which of the following best describes XYZ
Alex787 [66]
<h2>Answer:</h2>

D. Inscribed angle

<h2>Step-by-step explanation:</h2>

An inscribed angle has a vertex on the circumference. For any arc, every inscribed angle is exactly half of the central angle. In other words, if the central angle is x^{\circ} and the inscribed angles is y^{\circ}, then it is true that:

y^{\circ}=\frac{x^{\circ}}{2}

In this problem y^{\circ}=36^{\circ}, then the central angle is x^{\circ}=2y^{\circ} \ \therefore x^{\circ}=2(36^{\circ}) \therefore x^{\circ}=72^{\circ}
