A^2 + b^2 = c^2....a and b are the legs and c is the hypotenuse
2^2 + b^2 = 4^2
4 + b^2 = 16
b^2 = 16 - 4
b^2 = 12
b = sqrt 12 <=== square root of 12 units
Step-by-step explanation:
By elimination method,
x+y=15
-x+y=5
------------
2y=20
i.e y=10
Now,
x+y=15
or, x+10=15
or, x=5
Answer:
Where is the X supposed to be located
