Answer:
17
Step-by-step explanation:
(x+28y)/x =50
Multiply each side by x
(x+28y)/x *x =50*x
x+28y = 50x
Subtract x
x-x+28y = 50x-x
28y = 49x
Divide by y
28y/y = 49x/y
28 = 49 x/y
Divide by 49
28/49 = x/y
We want to find
(y+28x)/y
Rewriting as
y/y +28 (x/y)
1 + 28(x/y)
Replacing x/y with (28/49)
1 + 28(28/49)
1 +28*28/49
1+784/49
1+16

Answer:
2
Step-by-step explanation:
let the other leg be x
Using Pythagoras' identity
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 1² = 3²
x² + 1 = 9 ( subtract 1 from both sides )
x² = 8 ( take the square root of both sides )
x = 
= 
= 
× = 2 ← exact value
