Triangles ABC and ACD are right triangles. AB is 28 meters long. AC is 21 meters long. Find the lengths of BC and AD.

The length of BC = 18.52 m & AD = 28 m.

Step-by-step explanation:

Since Δ ABC & ΔACD are the right angles.

So BC = CD

From Δ ABC  

x = 18.52 m

Thus BC = x = 1852 m

CD = BC = 18.52 m

Now from the ΔACD

AD =

AD = 28 m

Therefore the length of BC = 18.52 m & AD = 28 m.
