I think the best answer would be (A) (2.1+5.9+3.7) but the only difference is that one is negative an the other is positive
I don't know if my answer is completely correct, but I think it's 100. All triangles add up to 180, and an isosceles triangle has 2 equal sides. 40 would be the 2 sides, and 180 subtracted from 80 equals 100.
On a map, they would be 7 inches apart, if that's what you're asking.

Start by finding the common denominators (in this case, 6)
So;
1/6x + 15/6 = -2/6
1/6x = -17/6
x = -17
