Answer:60

Step-by-step explanation:all sides of the triangle have to be 180 degrees

Troyanec [42]2 years ago

Answer:

60 degrees

Step-by-step explanation:

120 and the angle next to it are supplementary angles meaning they add up to 180. So take 180 - 120 to get 60. A triangle's angles add up to 180. So you take the 60's from the 180 to get the other sixty. In other words 180 - (60 + 60) = 60.

Hope this helped. I feel like I explained this kinda weird so ask questions if you have them.

Al principio Eduardo y Adrián tenían el mismo número de dulces. Eduardo le dio a Adrián la mitad de los dulces que tenía. Despué
Dennis_Churaev [7]

Answer:

Al final, Eduardo tenía 20 dulces.

Step-by-step explanation:

Dado que al principio Eduardo y Adrián tenían el mismo número de dulces, y Eduardo le dio a Adrián la mitad de los dulces que tenía, y después, Adrián le dio a Eduardo la mitad de los dulces que tenía él en ese momento, así que a Adrián le quedaron 12 dulces, para determinar cuántos dulces tenía Eduardo al final se debe realizar el siguiente cálculo:

Eduardo 1X = Adrián 1X

Eduardo 0.5X = Adrián 1.5X

Eduardo 1.25X = Adrián 0.75X

0.75 X = 12

X = 12 / 0.75

X = 16

1.25 X = 16 x 1.25 = 20

Así, al final, Eduardo tenía 20 dulces.
