Answer:

6 units

Step-by-step explanation:

The formula for a trapezoid is ((b1+b2)/2)h.

Here, we see b1 = 8 and b2 = 17.

If the area of the trapezoid is 75, we can make the equation :

75 = ((8+17)/2)x , where we would solve for x.

First, we simplify the right side of the equation :

75 = (25/2)x

Multiply both sides by 2 to get rid of the "/2"

150 = 25x

Then divide both sides by 25.

6=x

Answer:

$\approx 9.0\:\mathrm{units}$

Step-by-step explanation:

The magnitude of 3D vector $\vec{v}$ can be given by the following:

$| \overline{v}| =\sqrt{{v_x}^2+{v_y}^2+{v_z}^2}$

Plugging in given values, we have:

$| \overline{v}|=\sqrt{3^2+7.2^2+4.5^2},\\| \overline{v}| \approx \fbox{$9.0\:\mathrm{units}$}$ .
