Answer:

Step-by-step explanation:

These triangles are congruent by the 3 sides of 1 triangle being congruent to 3 sides of the other. SSS

The fact that one has been rotated in terms of the other means nothing.

What is the value of x and the length of segment DE?

aniked [119]

Answer:

x = 6.6; DE = 16.6

Step-by-step explanation:

Assume the diagram is like the figure below.

1. Calculate the value of x

In a right triangle, the altitude drawn from the right angle to the hypotenuse divides the triangle into two similar triangles.

Thus, ∆CDF ~ ∆FDE, and

$\begin{array}{rcl}\dfrac{CD}{DF} &=& \dfrac{FD}{DE}\\\\\dfrac{5}{9} &=& \dfrac{9}{2x + 3}\\\\5(2x + 3) & = &81\\10x + 15 & = & 81\\10x & = & 66\\x & = & \mathbf{6.6}\\\end{array}$

2. Calculate the length of DE

DE = 2x + 3 = 2(6.6) + 3 = 13.2 + 3 = 16.2

I don’t understand to this problem

JulsSmile [24]

You would use TOA from trig so your equation would be

Opposite = tan(angle) X adjacent

X = tan(15) X 400
It should equal 6000 but check that using the equation on a calculator :)
