How do you find points x, y, and z? you and i will mark as brainliest and 15 points!

The answer is  x = 21, y = 5√21  and  z = 2√21.

Step-by-step explanation:  As given in the question and shown in the attached figure, ΔABC, ΔABD and ΔACD are all right-angled triangles. Here, AB = 10  and  BD = 4, We need to find the values of 'x', 'y' and 'z'.

From the right-angled triangle  ΔABD, we have after using Pythagoras theorem that

Again, from the right-angled triangles ΔABC and ΔACD, we have

and

Subtracting the above equation from the previous one, we have

And finally,

Thus, x = 21, y = 5√21  and  z = 2√21.

55? i think maybe
