How many degrees does each angle of an equilateral triangle measure?

B: 60

Step-by-step explanation:

In fact, the angles are all "fixed" - they are each 60 degrees. ... An equilateral triangle has all three sides the same, therefore all three angles are the same. When you add up the angles of any triangle, you get 180 degrees, so 180 divided by 3 is 60 - the size of every angle of any equilateral triangle..  Hope this helps!!

if you was gonna solve for a, a is a   < -12
