Answer:
Creo que la respuesta es A
Step-by-step explanation:
porque u lo divide todo y es el primero porque es igual a un número entero
In an equilateral triangle all the sides are equal. This means that all the angles add up to 180 degrees.
Divide 180 by 3 and you get 60.
You want an exterior angle so you cut the angle in half ( it is now 30 )
Because the base and the line are parallel (form right angle if drew line connecting them) x is equal to
90-30=60
