Answer:

To determine the height we will use a² = b²+c²

(10m)²= (5m)²+(h)²

<=> 100m²=25m²+h²

<=> 100m²-25m²=75m²=h²

<=> √ 75m² = h = 8,660m

Answer:

5^2 + h^2 = 10^2

Step-by-step explanation:

This is a clear example of the Pythagorean Theorem, a relation of all sides in a right triangle. The equation itself is a^2 + b^2 = c^2. By simply plugging in the given values into the triangle, you would get the answer.

In this in this equation y equals 14 x what is the constant of proportionality
lions [1.4K]

Answer:

We conclude that the value of the constant of proportionality.

  • k = 14

Step-by-step explanation:

We know that if 'y' varies directly with 'x', we use the equation

y ∝ x

y = kx

where 'k' is called the constant of proportionality.

Given the equation

y = 14x

comparing with the equation

y = kx

Thus,

k = 14

Therefore, we conclude that the value of the constant of proportionality.

  • k = 14

Fill in the blanks:<br> V=___W=___x=___y=___z=___
Vesna [10]

9514 1404 393

Answer:

  v = 39; w = 47; x = 94; y = 39; z = 47

Step-by-step explanation:

The figure shows v° and 51° are complementary, as are z° and 43°.

  v° = 90° -51° = 39°

  z° = 90° -43° = 47°

Vertical angles are congruent.

  y° = v° = 39°

  w° = z° = 47°

And the angle x° is a vertical angle with the sum of 51° and 43°.

  x° = 43° +51° = 94°
