2 x (n - 6)
(2 x n - 2 x 6)
(2n - 2 x 6)
2n - 12

Find the distance between the points (2,2) (5,5)

Ugo [173]

Answer: root18

Step-by-step explanation:

A (2,2) x1=2 y1=2

B (5,5) x2=5 y2=5

D(AB) = root [(x2-x1)^2 + (y2-y1)^2]

= root [(5-2)^2 + (5-2)^2]

= root [3^2 + 3^2]

= root (9+9)

D(AB)=root18

BD bisects m m Find m

amm1812

The text of the question is not visible in the answering window. I'll reproduce it here:

BD bisects <ABC.

m <ABD= 2.5x + 8.6

m<CBD = 3.5x - 3.4

Find m<ABC

Answer:

$m\angle ABC = 77.2^\circ$

Step-by-step explanation:

We have an angle ABC and a line BD bisecting it.

If an angle is bisected, then the two formed angles are congruent, that is

$m\angle ABD=m\angle CBD$

Substituting the algebraic expressions for both angles:

$2.5x + 8.6=3.5x - 3.4$

Subtracting 8.6 and 3.5x:

$2.5x - 3.5x = -8.6 - 3.4$

Operating:

$-x = -12$

$x = 12$

The two angles are:

$m\angle ABD=2.5x + 8.6=2.5(12) + 8.6=38.6^\circ$

$m\angle CBD=3.5x - 3.4 = 38.6^\circ$

As expected, both angles have the same measure.

The measure of the total angle ABC is twice any of those:

$m\angle ABC = 2*38.6^\circ=77.2^\circ$

$\mathbf{m\angle ABC = 77.2^\circ}$
