Question

Find x in the figure ​

Answer 1

Answer:

x = 16

Step-by-step explanation:

We will use Pythagoras Theoram :

AB^2 = BC^2 + CA^2

20^2 = 12^2 + x^2

400 = 144 + x^2

x^2 = 400 - 144

x^2 = 256

x = √256

x = √16×16

x = 16

Answer 2

Answer:

x=16

Step-by-step explanation:

We will use Pythagoras Theoram :

AB^2 = BC^2 + CA^2

20^2 = 12^2 + x^2

400 = 144 + x^2

x^2 = 400 - 144

x^2 = 256

x = √256

x = √16×16

x = 16
