Answer:

m∠DBC = 51°

Step-by-step explanation:

<u>Circle Theorem vocabulary</u>

  • Chord: A straight line joining two points on the circle.
  • Inscribed angle: The angle formed when two chords meet at one point on a circle.
  • Intercepted arc: The arc that is between the endpoints of the chords that form the inscribed angle.

<u>Inscribed Angle Theorem</u>

The measure of an <u>inscribed angle</u> is half the measure of the <u>intercepted arc</u>.

Therefore:

\sf \implies \angle DBC=\dfrac{1}{2}\:\overset{\frown}{BC}

\sf \implies \angle DBC=\dfrac{1}{2}\:(102^{\circ})

\sf \implies \angle DBC=51^{\circ}

\huge\underline{\underline{\boxed{\mathbb {SOLUTION:}}}}

To determine ∠DBC, we will apply the theorem relating the inscribed angle to the intercepted arc:

\longrightarrow \sf{Intercepted \: arc= (inscribe \: angle)}

\longrightarrow \sf{Intercept \: arc= 102^\circ}

\longrightarrow \sf{Inscribed \: angle= \angle DBC }

\longrightarrow \sf{102=2( \angle DBC)}

\longrightarrow \sf{\angle DBC= \dfrac{102}{2} }

▪ \longrightarrow \sf{\angle DBC = 51^\circ}

\huge\underline{\underline{\boxed{\mathbb {ANSWER:}}}}

\boxed{\bf{\large m \: \angle DBC= 51^\circ}}

: 11 = 1 /3 : 6<br><br> plz help
GenaCL600 [577]
<h3>Let the number be x</h3>

x:11 =  \frac{1}{3} :6

  • Divide the numbers

\frac{x}{11}  =  \frac{ \frac{1}{3} }{6}  \\  \frac{x}{11}  =  \frac{1}{18}

  • Multiply all terms by the same value to eliminate fraction denominators

11 \times  \frac{x}{11}  = 11 \times  \frac{1}{18}

  • Cancel multiplied terms that are in the denominator

x = 11 \times  \frac{1}{18}

  • Multiply the numbers

x =  \frac{11}{18}
