a trapezoid with base measure of 23 km and 29km an area of 390km . find the height of the trapezoid.

Hello!

To find the area of a trapezoid you use the equation

$A = \frac{a+b}{2} h$

Put in the values you know

$390 = \frac{23+29}{2} h$

Add

$390 = \frac{52}{2} h$

Divide

$390 = 26 * h$

Divide both sides by 26

15 = h

The answer is 15km

Hope this helps!
