Given that ABCD is a rhombus, what is the value of x?
SashulF [63]

Answer:

B

Step-by-step explanation:

A rhombus is divided into four congruent triangles. The two given angles are complementary, meaning they add up to 90 degrees. Set up an equation:

(4x-25)+x=90

4x-25+x=90   Take out the parentheses

5x-25=90   Combine like terms

5x=115   Add 25 to both sides so as to isolate the variable

x=23   Divide both sides by 5

Could 1.5, 2.5, 3.5 and 6, 10, 12 be the corresponding sides of two similar triangles
boyakko [2]

Answer:

No

Step-by-step explanation:

If the ratios of the corresponding sides are equal then they would be the sides of 2 similar triangles.

Calculate the ratio of corresponding sides.

\frac{6}{1.5} = 4

\frac{10}{2.5} = 4

\frac{12}{3.5} ≠ 4

Thus the sides are not the corresponding sides of similar triangles.

Juana compró una camioneta 4x4 a S/ 42 000; además, sabe que la camioneta se depreciará (bajará su precio) en forma lineal duran
prohojiy [21]

Answer:

Una relación lineal es de la forma:

y = a*x + b.

donde a es la pendiente y b es la ordenada al origen.

en este caso, y es el precio de la camioneta, x es el numero de años que pasaron, a es la razon de depreciación de la camioneta y b es el precio inicial de la camioneta, b = $42,000.

Sabemos que después de 5 años, el precio de la camioneta es 21,000, entonces podemos resolver:

$21,000 = a*5 + $42,000

a*5 = $21,000 - $42,000 = -$21,000

a = -$21,000/5 = -$4,200

Esto significa que el precio decae $4,200 por año

I need help finding the angles. The answer Isn't even
mart [117]

The 3 inside angles of a triangle equal 180.

Add the 3 angles together to equal 180:


X + (5x-20) + 4x = 180

Simplify the left side by adding like terms:

10x-20 = 180

Add 20 to each side:

10x = 200

Divide both sides by 10:

x = 20


Angle A = x = 20

Angle B = 4X = 4(20) = 80

Angle C = 5x-20 = 5(20) -20 = 100-20 = 80
