Answer:

x = 4
length = 19 ft
width = 11 ft

Step-by-step explanation:

The area is given by the product of length and width.

A = LW

209 = (4x +3)(4x -5)

209 = 16x^2 -8x -15

224 = 16x^2 -8x

You could rearrange and use the quadratic formula at this point, but we elect to "complete the square".

14 = x^2 -(1/2)x

14 +1/16 = x^2 -1/2x +(1/4)^2 . . . . . add the square of half the x-coefficient

(x -0.25)^2 = 14.0625

x = 0.25 ± 3.75 . . . . . . take the square root; add 0.25

Only positive values of x are useful here, so we have

x = 4

Then the dimensions are ...

length = 4x +3 = 4(4) +3 = 19 . . . feet

width = 4x -5 = 16 -5 = 11 . . . feet

The value of x in the triangle is (a) 22

<h3>How to solve for x?</h3>

The complete question is in the attached image.

From the attached image of the triangle, we have:

$\sin(45) = \frac{x}{22\sqrt 2}$

Evaluate sin(45)

$\frac{1}{\sqrt 2} = \frac{x}{22\sqrt 2}$

Solve for x

$x = \frac{22\sqrt 2}{\sqrt 2}$

Divide

x = 22

Hence, the value of x is (a) 22

PLZ HELP its Triangle Properties and where using the 45º-45º-90º Triangle Theorem and the 30º-60º-90º Triangle Theorem.

Answer:

The answer to your questions is below

Step-by-step explanation:

4.-

In a 45°-45°-90° triangle, the length of the legs are "x" and the length of the hypotenuse is x $\sqrt{2}$

Then, in this problem, the length of the leg is 7 then the length of the hypotenuse will be 7 $\sqrt{2}$

5.- In a 30°-60°-90° triangle, the length of the hypotenuse is 2x, the length of the longer leg is x $\sqrt{3}$ and the length of the shorter leg is x.

In this problem we have the length of the hypotenuse = 20 and find x.

2x = 20

x = 20/2

x = 10

longer leg = x $x\sqrt{3} = 10\sqrt{3}$

6.- nonzero

7.- hypotenuse = 20 cm

Find x

2x = 20

x = 20/2

x = 10

Shoter leg = x = 10 cm
