The best answer to your question is 'D'
4) x + x + x = 180°
An equilateral triangle has three sides of equal length. Its interior angles are also equal. Since interior angles of a triangle should sum up to 180°, then each angle is 60°, making each angle congruent with one another.
So if x is equal to one angle and triangles have three angles then,
x + x + x = 180°
or 3x = 180°
You use the slope formula, (y2-y1/x2-x1)
10(6)=60
3(6.75)=20.25
6(2.75)=16.5
60+20.25+16.5=96.75
