Answer 1

I can solve this but I don’t have the triangle image or the coordinates of A, B, and C. Could you either paste the coordinates or upload the picture (or the “Long Desc” text)?

Meanwhile, here is exactly what I will do once I have the coordinates:

1. If A = (xA, yA) and C = (xC, yC), find midpoint D of AC:
D = ((xA + xC)/2, (yA + yC)/2).

2. If B = (xB, yB), compute BD using the distance formula:
BD = sqrt((xB − xD)^2 + (yB − yD)^2).

3. Round BD to one decimal place.

If you post the coordinates of A, B, and C (or the long description), I’ll compute BD and give the rounded answer.
