Dos triángulos son semejantes, si sus ángulos son iguales y sus lados proporcionales. Verdadero o falso?
iren2701 [21]

Answer: verdadero.

Step-by-step explanation:

En geometría se dice que dos figuras son semejantes si tienen la misma forma pero no necesariamente el mismo tamaño.

Ahora, lo que define la forma de un triángulo son sus ángulos, entonces si dos triángulos tienen los mismos ángulos, estos triángulos van a tener la misma forma.

Y los lados siendo proporcionales entre ellos (recordar que una relación proporcional es y = k*x) habla de la relación entre los tamaños de los dos triángulos.

Entonces si, "dos triángulos son semejantes, si sus ángulos son iguales y sus lados proporcionales" es verdadero.

Please help
Firlakuza [10]

Answer:

Step-by-step explanation:

y = -2/3 x       multiply both sides the first equation by 6

6y = -4x                    Add 4x to both sides.

6y + 4x = 0

<u>-9y +4x = - 40   </u>        Subtract the bottom equation

15y =  - 40                 Divide by 15

y = -40/15

y = - 2.7

======================

6y = -4x

6*(-2.67) = -4x

-16 = - 4x

x = - 16/-4

x = 4
