A. If AC bisects BD and BD=26, find GD.
B. If AC bisects BD, AB=26 and BD=48, find AG.
C. AC bisects BC and AC=15M. Find the length of arc AB to the nearest meter.

Where are A, B, C, D and G?

Are talking of a circle?

Which is the arc and which is the chord?

In the circle E is chord at the top of the circle to the left hand side, A is the midpoint of the circle, that connects to B which touches slantly the buttom left of the circle. B goes straight across to the other side of the circle to meet D. A runs directly straight to the bottom of the circle to meet C. G is mid point of B and D and A and C. ABG forms a right angle triangle. I hope this helps.


Question c. the midpoint is C, BC is a line directly to the left, AC is a line straight down from the midpiont to the bottom of the circle. 15m alongside CA. The sector form a 90 degree angle.

I am even more confused!

Perhaps you should attach a diagram.
