Answer:

WV = 169.591 feet

Step-by-step explanation:

As VWX has ∠X equal to 90°, so that it is the right triangle.

In the right triangle, there is a formula as following:

sin <em>acute angel = opposite side/ hypotenuse side</em>

So that, in triangle VWX:

+) <em>sin ∠W = XV / WV </em>

as ∠W =20° and XV is equal to 58 feet, replace it into the formula above, we have:

sin ∠W = sin 20° = 58/ WV

=> WV = 58/ (sin 20°)

sin 20° ≈ 0.342

=> WV ≈ 58/ 0.342 = 169.591 feet

Two sides of an acute triangle meaure 5 inches and 8 inches. The length of the longest side is unknown. What is the greatest pos

gladu [14]

The greatest whole possible whole number length of the unknown side is 9 inches.

<h3>How to identify if a triangle is acute?</h3>

Let us have:

H = biggest side of the triangle

And let we get A and B as rest of the two sides.

Then we get:

$A^2 + B^2 < C^2$

then the triangle is acute

Two sides of an acute triangle measure as 5 inches and 8 inches

The length of the longest side is unknown.

We have to find the length of the unknown side

WE know that the longest side of any triangle is a hypotenuse

For an acute triangle we know:

$A^2 + B^2 < C^2$

Here in this sum,

a = 5 inches

b = 8 inches

c = ?

Substituting we get,

$A^2 + B^2 < C^2\\\\5^2 + 8^2 < C^2\\\\25 + 64= C^2$

c < 9

Hence, The greatest whole possible whole number length of the unknown side is 9 inches.

How much solutions does this equation have?

Evgesh-ka [11]

Answer:

All solutions or infinite.

Step-by-step explanation:

Turn 2y = -4x + 6 into standard form - divide by 2

Y = -2x + 3

2x + y = 3

Substitute the y equation in for y.

2x - 2x + 3 = 3

The x variables cancel out.

3 = 3

Which is true so it means all solutions.

Hope this helps.
