Given:
m∠APB = 19°
To find:
The arc measure of DBC.
Solution:
∠APB and ∠DPC are vertical angles.
By vertical angle theorem:
m∠APB = m∠DPC
m∠DPC = 19°
DB is the diameter of the circle.
Angle measure of diameter = 180°
m∠DPB = 180°
m∠DPC + m∠CPB = m∠DPB
19° + m∠CPB = 180°
Subtract 19° from both sides.
19° + m∠CPB - 19° = 180° - 19°
m∠CPB = 161°
<em>The measure of central angle is equal to the measure of intercepted arc.</em>
m∠CPB = m(ar CPB)
m(ar CPB) = 161°
The arc measure of DBC is 161°.

Answer:
The answer is no this number is not rational.
Step-by-step explanation:
Because, To show that the rational numbers are dense:
It cannot be expressed as a fraction with integer values in the numerator and denominator. When an irrational number is expressed in decimal form, it goes on forever without repeating.
Answer:
Step-by-step explanation:
She likely has more books than the Library of Congress.
First of all you have to take 1/2 the number
(1/2) 392,396 = 196198
sqrt(196198) = 443 rounded to the nearest whole number.
Answer:
y = 4/p−x/2p
(4 over p is a fraction as well as X over 2p)
