an engineer decides to use similar triangles to find the distance across the river she makes the diagram below which triangles t

sergiy2304 [10]

<h2>Explanation:</h2><h2 />

The missing diagram is shown below. Remember that shapes are similar if you can turn one into the other by moving, rotating, flipping, or scaling. So this means you can make the object bigger or smaller. So in this case, we know that ΔABC is similar to ΔDEF. If so, we can establish the following proportion:

$\frac{h}{56.7}=\frac{17.2}{52.4} \\ \\ h=56.7\times \frac{17.2}{52.4} \\ \\ h=18.61m$

Our goal is to find x. So by Pythagorean theorem:

$x=\sqrt{17.2^2+18.61^2} \\ \\ \boxed{x=25.34m}$

Conclusion:

<em>Distance across the river is 25.34m </em>

The function of g(x)=8^2-48+65 written in vertex form is g(x)= 8(x-3)^2-7 what is the vertex of g(x)

Iteru [2.4K]

The vertex is where g(x) = 0
i.e. where 8(x^3)^2-7 is equal to x

who wrote this question, there aRE OBVIOUS errors.

(6x+2)^2=36x^2+Bx+4 How Would You Answer That. I'm Not That Good At Algebra.

Verizon [17]

Let's multiply out the equation 6x+2 times 6x+2 using the square. Draw a 2 by 2 bow and put the equation across the bottom and verically. Multiply across to get this. 6x times 6x =36x^2 6x times two =12x do it again and get 12x. 2*2=4. That means x would equal 24.

Let x = 6.

Mars2501 [29]

Put the value of x = 6 to the eqpression 5x² + x - 7:

5(6)² + 6 - 7 = 5(36) + 6 - 7 = 180 + 6 - 7 = 179

<h3>Answer: 179</h3>
