Answer:

4.5 m

Step-by-step explanation:

Distance from center to the the bottom part where headroom begins is 3.9 m-2.6 m=1.3 m

Since the radius is 2.6 m and acts as hypotenuse(see attached image), then the other length will be

$\sqrt {2.6^{2}-1.3^{2}=5.07}=2.25166605
$

Approximately 2.25 m

The half width is 2.25 m hence full width will be 2.25*2=4.5 m

Samantha drew Triangle JKL with the coordinates (2,3), (4, 3) and (5,2). She reflected this image over the x-axis to create an i

zavuch27 [327]

Answer:

J'(2,-3), K'(4, -3) and L'(5,-2)

Step-by-step explanation:

The given triangle has vertices at J(2,3), K(4, 3) and L(5,2).

The transformation rule for a reflection in the x-axis is:

$(x,y)\to (x,-y)$

We substitute the points to obtain the coordinates of the image triangle J'K'L'

$J(2,3)\to J'(2,-3)$

$K(4,3)\to K'(4,-3)$

$L(5,2)\to L'(5,-2)$

In other words, we negate the y-coordinates of triangle JKL to obtain the coordinates of J'K'L'
