<h2>Answer :</h2>

We'll be using the Pythagoras property to solve this question.

According to the Pythagoras property,

H² = B² + P²

H denotes hypotenuse

B denotes base

P denotes perpendicular

Here,

H = x
P = 35 cm
B = 12 cm

→ (x)² = (35 cm)² + (12 cm)²

→ x² = 1225 cm² + 144 cm²

→ x² = 1369 cm²

→ x = √(1369 cm²)

→ x = 37 cm

Therefore, value of x is 37 cm.

For this case we have by definition, if "y" varies directly with "x", then it is true that:

$y = kx$

Where:

k: It is the constant of proportionality

We have the following equation:

$y = 2.5x$

So, as mentioned above we have to:

$k = 2.5$

Answer:

$k = 2.5$
