Step-by-step explanation:

To find Lenght AC

Let analyse the triangle ABC

Triangle ABC is a right angle triangle at B.

Then, applying Pythagoras theorem

AC²=AB²+BC²

From the graph,

Note that each division on both x and y axis is 1unit

Then,

AB= 8unit

BC= 3unit

So, Applying the Pythagoras theorem for ∆ABC

AC²=AB²+BC²

AC²=8²+3²

AC²=64+9

AC²=73

AC=√73

AC= 8.54units

Approximately AC=8.5units

Now to get BD

Let analyse the triangle BAD

Triangle BAD is a right angle triangle at A.

Then, applying Pythagoras theorem

BD²=AB²+AD²

From the graph,

Note that each division on both x and y axis is 1unit

Then,

AB= 8unit

AD= 6unit

So, Applying the Pythagoras theorem for ∆BAD

BD²=AB²+AD²

BD²=8²+6²

BD²=64+36

BD²=100

BD=√100

BD= 10 units

Then, the answer is 10units and 8.5 units

answer: none of these answers are correct only the second half is
