Can you please help me solve this
Person A and B started in the same spot and travelled in different directions, they both travelled the same amount of distance. The distance between the two is 100 meters now. The angle from where point A is to the point where they started to Point where B is 15 degree. This looks like an isosceles triangle problem or a circle with two radii problem. The question asks how far have the two travelled?
Some answers have 360 degree and Pi but I am not able to figure out how to solve this. Please help.

Hi phalgun,
What is the source of this question? I ask because it doesn't have the 'style' of a GMAT prompt. If it is a GMAT question, then you should include the 5 answer choices (since sometimes those answers provide a big clue as to how you might go about solving the problem). If it's not a GMAT question, then you really should be using GMAT-centric study materials instead of this material.

Are you sure it's 1°? That sounds more like a trig problem than a GMAT problem: you've basically got an isosceles triangle with sides x, x, and 130, and angles of 1°, 89.5°, and 89.5°, and you're asked to find 2x. I don't know how you'd find the side ratios using geometry that's within the scope of the GMAT.
If the angle were 30° (or even 10°), however, we could do it GMAT-style.

That doesn't quite add up: you're given exact numbers but asked for a formula? Something seems off here: if this is really just a HW problem from a class, I'm happy to answer it, but I'd need to see the text and be apprised of what geometry (or trig) you're expected to know.
