Answer:
x = 15
Step-by-step explanation:
We assume you want to find the value of x.
Know (or prove) that in this geometry, all of the right triangles are similar. That means the ratios of corresponding sides are proportional.
short side / hypotenuse = 9/x = x/25
x^2 = (9)(25) . . . . . . . . . . multiply by 25x ("cross multiply")
x = √((9)(25)) = (3)(5) . . . take the square root
x = 15

Answer:
Option D i.e. y = 1/2 x is the correct answer.
Step-by-step explanation:
We know that when 'y' varies directly with 'x', we get the equation
y ∝ x
y = kx
where k is the constant of proportionality.
In our case, the only equation which maps in accordance with y = kx is y = 1/2x.
i.e.
y = 1/2 x
here k = 1/2
Thus, k = 1/2 is the constant of proportionality.
Therefore, option D i.e. y = 1/2 x is the correct answer.
