We can Notice that AB = AC

We know that if Two sides of a Triangle are Equal then Angles corresponding to those Sides are Equal.

⇒ ∠ABC = ∠ACB

⇒ (5x)° = 25°

⇒ x° = 5°

We know that Sum of Three Angles in a Triangle is equal to 180°

⇒ 25° + (5x)° + (3y + 70)° = 180°

⇒ 25° + 25° + (3y)° + 70° = 180°

⇒ (3y)° + 120° = 180°

⇒ (3y)° = 180° - 120°

⇒ (3y)° = 60°

⇒ y° = 20°

KIM [24]

Answer:

Paso 1:

Encuentra el área del patio trasero

Dado eso, el patio trasero mide 24 por 30 metros.

Área = largo x ancho

Área = 24 x 30 = 720

Por lo tanto, el área del patio trasero es de 720 metros cuadrados.

Paso 2:

Dado que el área de césped = 368 metros cuadrados

Luego, área de jardín = área de patio trasero - área de césped

área del jardín = 720 - 368

área de jardín = 352 metros cuadrados

Paso 3:

Encuentra las dimensiones del jardín

Sea "x" el ancho de la franja de césped

Entonces, las dimensiones del jardín son:

Longitud del jardín = 24 - 2x

Ancho del jardín = 30 - 2x

Luego,

área del jardín = (24 - 2x) (30 - 2x)



Factoriza el lado izquierdo

(x - 23) (x - 4) = 0

Por propiedad de factor cero,

x = 23 o x = 4

La solución x = 23 hace que las dimensiones del jardín sean negativas, por lo que la rechazamos
