Answer:
-13
Step-by-step explanation:
x=-8/3
<em>well first we move the like terms to one side</em>
3x=-2-6
<em>then we calculate the numbers</em>
3x=-8
<em>in order to make "x" alone we divide all of then by 3</em>
D. 60, 60, 60
In an equilateral triangle, all sides are equal and equal to 180 when added together. because 60×3 is equal to 180, D is the right answer. I hope this helps you!
