Answer:
(1,2)
y=2
x=1
Step-by-step explanation:
x+y=3
3x+5y=13
solve the equation
x=3-y
3x+5y=13
substitute the value of x into an equation
3(3-y)+5y=13
distribute
9-3y+5y=13
add -3y to 5y
9+2y=13
subtract 9 from both sides
2y=4
divide both sides by 2
y=2
substitute the value of y into an equation
x=3-2
subtract 3 to 2
x=1

Step-by-step explanation:
I'M HURRRRYYYINNNNNG DON'TT WORRY!!! :D
Use the Pythagorean theorem:
a²+b²=c²
Plug it in:

144+256=400
c²=400
c=√400
c=20
