Los puntos A (5, 3) y B (-3, -3) representan los extremos de un trozo de madera que será usado por un carpintero para elaborar u
neonofarm [45]

Answer:

Las coordenadas del punto son P(2.\overline 3, 1)

Step-by-step explanation:

Las coordenadas de los extremos de la pieza de madera son A (5, 3) y B (-3, -3)

El punto, P, en el que se agregará la muesca = 1/3 de la longitud de AB

Por tanto, las coordenadas del punto, tomando A como punto de referencia, se dan como sigue;

P (5 + (-3 - 5) × 1/3, 3 + (-3 - 3) × 1/3) = P(2.\overline 3, 1)

Las coordenadas del punto son P(2.\overline 3, 1).

Pls Help Choose the correct word to complete the statement: If BC intersects circle A only at point B, and mCBA = 90°, then CB i
cricket20 [7]

Line CB touches circle A only at one point (point B), hence CB is a tangent.

<h3>What is a circle?</h3>

A circle is the locus of a point such that its distance from a fixed point (center) is always constant.

When a line intersects a circle in exactly one point the line is said to be tangent to the circle

Hence since Line CB touches circle A only at one point (point B), hence CB is a tangent.
