Answer:

x = 8 and y= 12

Step-by-step explanation:

For x use the Pythagorean theorem:

[tex]x^2+6^2=10^2[/tex]

[tex]x^2+36=100[/tex]              subtract 36 from both sides

[tex]x^2=64\to x=\sqrt{64}\\\\x=8[/tex]

We know: x + y = 20. Substitute:

[tex]8+y=20[/tex]              subtract 8 from both sides

[tex]y=12[/tex]
