Answer:

.02 hours

or

1.2 minutes

800 meters is .8 kilometers (because there are 1000 meters in a kilometer).

Now just do dimensional analysis.

.8 km 1 hour

-------- x -------- = .02 hours

. 1 36 km

To find minutes, multiply .02 by 60.

(.02)(60)=1.2 minutes

Which relationship is always true for the angles r, x, y, and z of triangle ABC?
mariarad [96]

That's the second one,


180 - x = r


Whenever two lines cross we get congruent opposite angles and supplemental adjacent angles, i.e. they add to 180 degrees.


The first one is almost right; we have r+y+z=180 and r+x=180 so x=y+z not quite what was written.
