Answer:

it may be B but I think it's C

Step-by-step explanation:

not sure if this is right, but I would say not congruent. it may be sas but in order for it to be sas then the Angle must be in-between the two congruent sides

Both triangles are congruent by (SAS) side-angle-side postulate.

The correct option is B.

Two triangles are said to be congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure. These triangles can be slides, rotated, flipped and turned to be looked identical.

Given,

Two triangles

ABC and DEC

AB = DE    (Given)

BC = EC     (Given)

∠ACB = ∠DCE  (Vertical angles at intersection of DB and AE)

By, Side-Angle-side theorem of congruent triangles,

ΔABC ≅ΔDEC

Hence, by side-angle-side (SAS) postulate, both triangles are congruent.

El problema parece incompleto, asi que lo respondere en una forma general.

Sabemos que para un rectángulo de largo L y ancho W, el área se calcula como:

A = L*W

En este caso, sabemos que el área del rectángulo es:

A = 156cm^2

Entonces tenemos:

156cm^2 = L*W

No tenemos más información del rectángulo, entonces solo podemos llegar a algo como:

L = (156cm^2)/W

Que nos habla de la relación entre el largo y el ancho del rectángulo.

Answer:

D

Step-by-step explanation:

Our answer will be D. We can eliminate choices A and C since they are not products. In other words, they are not multiplying factors together; they are only adding or subtracting.

Answer B does not work, as when it is multiplied out, we get -2x + 16.

When we find the product of D, we distribute the negative and get the correct product, -2x - 16

Answer:

[tex]\angle BDC=80^{\circ}[/tex]

Step-by-step explanation:

We are given that

[tex]\angle ABC=69^{\circ}[/tex]

[tex]\angle ACB=31^{\circ}[/tex]

We have to find the angle BDC.

In triangle ABC

Sum of interior angles of triangle=180 degrees

[tex]\angle ABC+\angle ACB+\angle BAC=180^{\circ}[/tex]

[tex]69+31+\angle BAC=180[/tex]

[tex]100+\angle BAC=180[/tex]

[tex]\angle BAC=180-100[/tex]

[tex]\angle BAC=80^{\circ}[/tex]

[tex]\angle BAC=\angle BDC=80{\circ}[/tex]

Angles subtended on the same are ac are equal.

[tex]\angle BDC=80^{\circ}[/tex]

Answer:

b is 135 and c is 45.................thanks

Answer:

[tex]b=135\\c=45[/tex]

Step-by-step explanation:

The angle that measures 135 degrees and angle b are opposite angles. Opposite angles are congruent. Therefore, angle b=135.

[tex]b=135[/tex]

A straight line has an angle measure of 180 degrees. This means that 135+c would equal 180 degrees.

[tex]135+c=180[/tex]

Subtract both sides by 135

[tex]135+c-135=180-135\\c=45[/tex]

Answer:

formula

[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]

Step-by-step explanation:

choose two point of A, let k(-2, -3) and l(1, 3)

[tex] m = \frac{ - 3 - 3}{ - 2 - 1} = \frac{ - 6}{ - 3} = \frac{1}{2} [/tex]

choose two point of B, let c(0, 5) and d(5, 0)

[tex]m = \frac{5 - 0}{0 - 5} = \frac{5}{ - 5} = - 1[/tex]

Hence the gradient of A is
