What is the value of X?<br><br> What is the value of Y?<br><br> What is the value of Z?
baherus [9]

Answer:

The answer is

x = 12 \\ y = 20 \\ z = 15

Step-by-step explanation:

By using Pythagoras low

Then we can find that

{y}^{2}  =  {x}^{2}  +  {16}^{2}  \\  {z}^{2}  =  {x}^{2}   +  {9}^{2} \\  {y}^{2}   +  {z}^{2}  =  {25}^{2} \\  then \\  {x}^{2}  +  {9}^{2}  +  {x}^{2}  +  {16}^{2}  =  {25}^{2}  \\ 2 {x}^{2}  = 288 \\ x = 12 \\ By  \: substituting \:  x \:  into  \: the  \: previous \:  equations \\ then \:  \\ y = 20 \\ z = 15
