They are similar because triangle A has the measurements of 88 and 36 making the third angle 56 because 88+36-180=[56], triangle B will have the same angle measurements because it has the angles 56 and 88 making the last angle 36
Triángulo equilátero = todos los 3 lados son congruentes ("equilátero" = lados iguales)
Triángulo isósceles = solo 2 lados son congruentes
Triángulo escaleno = todos los lados son diferentes
El triángulo que se muestra aquí es isósceles porque 2 de los lados tienen la misma longitud de 7 cm.
Hello!
You solve this algebraically.
2(x - 3) + 4 = 2x + 3x - 5
Distribute the 2
2x - 6 + 4 = 2x + 3x - 5
Combine like terms
2x - 2 = 5x - 5
Subtract 2x from both sides
-2 = 3x - 5
Add 5 to both sides
3 = 3x
Divide both sides by 3
x = 1
The answer is D)1
Hope this helps!
The unknown factor is the divide sign
