I don't have the diagram or the numeric values from the problem, so I can't compute x yet. Could you either paste the problem text or upload the diagram?
Meanwhile, here are the two formulas you’ll most likely need (pick the one that matches the given info):
- If you know the radius R and the central angle θ (in degrees or radians) that subtends the chord:
x = 2R · sin(θ/2)
- If you know the radius R and the perpendicular distance d from the circle’s center to the chord:
x = 2 · sqrt(R^2 − d^2)
Also useful: if you know the chord’s sagitta (height from chord to arc) s, then d = R − s and plug into the second formula.
Send the diagram or the values for R, θ, d, or s and I’ll compute x and match it to the choices.
