The intersecting chords theorem states we can calculate the angle measure by... *
monitta

Answer:

A. Adding the values of the intercepted arcs and that is equal to twice the angle measure

Step-by-step explanation:

The intersecting chords theorem states that when four line segments are formed by two chords intersecting in a circle, the product of the two line segments on one chord is equal to the product of the two line segments on the other chord

The angles of intersecting chords theorem states that the angles formed by the intersecting chords one half the sum of the arcs intercepted by the chords

In the diagram attached, we have;

∠x = ∠y + ∠z

m\widehat{DHE} = 2·∠z, m\widehat{CIF} = 2·∠y

∴ ∠x = (1/2) × m\widehat{DHE} + m\widehat{CIF}

m\widehat{DHE} + m\widehat{CIF} = 2 × ∠x

The correct option is therefore adding the values of the intercepted arcs and that is equal to twice the angle measure.

Rocío trabaja en una peluquería, le pagan $50 por corte realizado, adicionalmente recibe $25 al día. Si el día miércoles recibió
skad [1K]

Usando conceptos de funciones lineales, se encuentra que hizo 5 cortes.

----------------

Una funcion lineale tiene el seguiente formato:

y(x) = ax + b

En que:

  • a eres lá inclinacion, o sea, lo que es pago por cada corte.
  • b eres el intercepto, o sea, lo pagamiento fixo por día.

----------------

  • Pagan $50 por corte realizado, o sea, a = 50.
  • $25 fixo al día, o sea, b = 25

Entonces, la funcion de su recibimiento y, como funcion de su numero de cortes x, es da por:

y(x) = 25 + 50x

----------------

  • Recibió $275, o sea, y(x) = 275

Entonces, el numero de cortes es:

y(x) = 25 + 50x

25 + 50x = 275

50x = 250

x = \frac{250}{50}

x = 5

Realizó 5 cortes.
